Fluorosilicone vs. Silicone for O-rings, Gaskets, Tubing and Seals


Fluorosilicone rubber (FVMQ) is a variation of silicone featuring stability, compression set resistance to temperature extremes, and enhanced resistances to non-polar solvents, fuels, oils, acids, and alkaline chemicals. This material is common in many industrial, automotive, and aerospace applications where static sealing and cushioning is required.

FVMQ contains trifluoropropyl groups, making it highly versatile for outdoor sealing applications or environments where exposure to sunlight, ozone, chlorination, or aromatic hydrocarbons is common. The basic properties of fluorosilicone include:

  • Temperature range: -60–200º C
  • Compression set: Fair/good
  • Strength: Fair
  • Low temperature properties: Excellent
  • Abrasion resistance: Poor
  • Gas permeability: Fair
  • Weather resistance: Excellent
  • Water resistance: Excellent
  • Ozone resistance: Excellent
  • Mineral oil resistance: Excellent
  • Chemical resistance: Excellent
  • Flame resistance: Excellent
  • Heat resistance: Excellent

A comparison between fluorosilicone and silicone in relation to their use in O-rings, gaskets, tubing and seals allow users to choose the best solution for specific applications.

Fluorosilicone vs. Silicone

Silicone elastomers—also known as silicone rubbers—are composed of silicone, carbon, hydrogen, and oxygen. They are non-reactive, stable, and resistant to extreme environments and temperatures from −55–300° C (−67–572° F). They share these characteristics with fluorosilicones.

Fluorosilicone rubber distinguishes itself from silicone because it also contains additional beneficial properties common to fluorocarbons. The addition of these compounds enhances FVMQ’s capacity to resist solvents, fuel, and oil. Fluorosilicone has a slightly lower maximum service temperature hot air resistance than silicone.

Fluorosilicone O-rings, Gaskets Tubing and Seals

Fluorosilicone’s distinctive properties make it ideal for use in the sealing solutions found in engines, machines, and other mechanical systems. Common fluorosilicone sealing components include:

  • O-rings. Shaped like a donut, O-rings are usually seated within a groove on one or both of the joined parts where they form a seal, where they block the escape of air and fluids by filling in the space between coupled components.
  • Gaskets. Gaskets provide a flexible seal between two joined components. They are usually flat and relatively thin, with bolt or pin penetrations through them. Compressed between two flat surfaces, gaskets provide sealing as well as vibration control.
  • Seals. This is a general term for any component that prevents fluid/air leakage fluids, blocks contaminants, or maintains pressure. O-rings and gaskets are types of seals, but the term usually applies to application-specific sealing solutions held in place by compression, such as oil seals found in engines.
  • Tubing.

O-rings, gaskets and seals fill the space between two joined parts in a machine or engine, allowing for the conveyance or transfer of fluids or air between them without leakage. Beyond fluid and vapor leakage, these components prevent debris from entering into mechanical systems and maintain consistent pressures to ensure optimal performance.

Recommended Uses of Fluorosilicone O-rings, Gaskets Tubing, and Seals

Certain systems, environments, and applications benefit from the use of O-rings, gaskets, tubing, and seals created with fluorosilicone, including:

  • Jet fuel systems
  • Dry heat environments
  • Broad temperature range environments
  • Some petroleum oil applications
  • Chlorinated solvents environments

Non-Recommended Uses Fluorosilicone O-rings, Gaskets Tubing and Seals

Though their properties provide ideal solutions in the above instances, there are other applications where the use of fluorosilicone O-rings, gaskets, tubing, and seals will produce less desirable or negative results, including applications containing:

  • Ketones (MEK)
  • Phosphate esters
  • Some acids
  • Auto/aircraft brake fluids
  • Amines (ammonia)

Benefits of Fluorosilicone O-rings, Gaskets, Tubing and Seals

There are certain special features provided by fluorosilicone O-rings, gaskets, and seals. Seals made of FVMQ provide benefits such as:

  • Excellent flexibility and compression set resistance
  • High-level aging, weather, and UV resistance
  • Resistance to animal and vegetable oils, fuels, oxidizing chemicals, aromatic and chlorinated solvents
  • Capacity to withstand aliphatic and aromatic fluorocarbons, diluted alkalis, toluene, benzene, ozone, diester oils, silicone oils, and oxidative environments

Silicone’s Properties and Advantages for Molded and Extruded Rubber

silicone propertiesSilicone is a versatile synthetic rubber used in nearly all industries for applications ranging from seals and tubing to insulating paints or films. Unlike similar organic materials such as natural rubber latex, which have a carbon-to-carbon backbone, silicone’s silicon-to-oxygen backbone makes it stable, resistant to damage, and flexible enough to be processed into end-use products with a variety of properties in a broad spectrum of temperatures from very high to very low.

Learn how our silicone tubing is helping medical, pharmaceutical and nutraceutical facilities respond to COVID-19.

Silicone can be processed into many forms, such as:

  • Solid silicone rubbers
  • Liquids
  • Lubricants
  • Water-proofing agents
  • And more

Common silicone products stay stable elastically and mechanically across a wide range of temperatures from -60° C to +200° C. Specialty silicone products, such as certain types of silicone rubber and fluorosilicone, also possess a high tensile strength and extreme low and high temperature performance. For example, certain high-consistency rubber (HCR) silicone products have a tensile strength of more than 1800 psi., and are functional in temperature ranges from -75° C up to 220° C or higher.

Some of the most common types of manufactured silicone products include:

  • Adhesives, including both liquid adhesives and pressure sensitive tapes
  • Caulks, protective or waterproof coatings, and sealants
  • Electrical Insulation
  • Molds for fabrication
  • Silicone resins
  • Silicone rubbers tubing, profiles, and molded seals
  • Surfactants

These products and more are used across every industry, including but not limited to:

  • Food Preparation And Handling Equipment
  • Electronics
  • Healthcare
  • Transportation
  • Consumer goods

Before companies select the final type of silicone material for a product, it’s important to know the properties of silicone.

Properties of Silicone

Silicone is the name for a general class of inorganic polymers that include materials both stable enough and flexible enough for industrial purposes. While there are several different types of silicone polymers, each one has a central strip, or backbone, of alternating silicon and oxygen.

Along the edges of this backbone are varying methyl groups that give silicone polymers their different properties and applications. Using organic methyl replacements can lead to unique properties, such as increasing the material’s flexibility at low temperatures or increasing solubility.

General silicone properties include:

  • Silicone polymers can be fabricated to remain soft and pliable throughout their lifetime without fatiguing, hardening, cracking, or requiring plasticizers. This makes this material optimal for products that undergo repeated loading/unloading, such as tubing in peristaltic pumps.


  • Hydrophobic properties. Silicone seals repel water to protect underlying materials without restricting breathability. This property is essential in waterproof coatings and films, and insulating components.silicone rubber hydrophobic properties


  • Low rotation barriers. Silicone’s molecular backbone has low rotation energy, which gives it greater rotational freedom that contributes to the material’s flexibility.silicone rubber-low rotation barriers


  • Resistance to aging. Silicone resists degradation caused by UV radiation, chemical exposure, and poor environmental conditions.

silicone rubber-resistance to aging

Physical Properties of Silicone

Silicones can be processed and formed into different shapes and sizes, which then retain properties such as:


Silicone’s silicon-oxygen chain backbone gives the material great flexibility, even once it’s been set and molded. Silicone components can be folded, bent, and twisted without suffering damage.


silicone rubber hardness options

Silicone materials use comparative scales called Shore hardnesses to characterize their hardness. The two commonly used Shore scales for silicones are Shore 00 for silicone sponge products and Shore A for dense products. Commonly used dense silicone materials typically have a Shore hardness of 30A-70A on a scale of 0-100A. Specialty grades can go as low as 10 Shore A to as high as 90 Shore A. For comparative purposes, 20 Shore A indicates a “feel” similar to a racquetball and 80 Shore A feels more like the tread on an automobile tire.

Color and Finish

silicone rubber color and finish

Silicones in their original state are translucent white. Silicone polymers can be colored and finished to have different hues and surface textures.

Electrical Insulation and Conductivity

silicone rubber-electrical insulation

Silicones in their original state are highly insulative electrically. As such, they are often used in applications where high dielectric strength is needed. What is unique about silicone is that they accept high levels of fillers and retain processability. As a result, they are often filled with conductive fillers to achieve very low resistance and are used as seals on electronics to provide EMI/RFI shielding.

Thermal Insulation and Conductivity

Silicones in their original state are highly thermally electrically. As such, they are often used in applications where low heat transfer is needed, such as in tubing for fluid conveyance in food handling or oven applications. What is unique about silicone is that they accept high levels of fillers and retain processability. As a result, they are often filled with materials to increase their thermal insulation even more, or conversely, with thermally conductive fillers to achieve very high heat transfer, such as for thermal interface (TIM) materials in electronics.

Melting Point

silicone rubber melting point

Because silicone is a thermoset elastomer, it does not truly melt. It will continue to function and retain its elastic and mechanical properties to the point where enough energy is imparted to the polymer that the polymer chain starts to break down. In general, silicone rubber can withstand temperatures as high as 300° C.

Set Shapes

silicone rubber-set shapes

Silicone polymers can be fabricated into set shapes and dimensions that hold their form after crosslinking. These forms include:

  • Tubes
  • Gaskets
  • Sheets
  • Complex molded components

With these properties, silicone is the ideal material for manufacturing O-rings, gaskets, tubes, and solid seals. These silicone O-rings and other parts are thin, flexible, and resistant to temperature extremes and chemical damage.

Silicone Rubber Properties

silicone temperature range


Silicone elastomers are one subgroup of silicone polymers. The material is stable, easy to handle, and usually formed into components through the extrusion or molding processes. Through a variety of fabrication processes, silicone rubbers can form custom rubber gaskets and seals, rubber tubing and silicone tubingrubber and silicone extrusions, and more.

Beneficial properties of silicone rubber include:

  • Flame retardancy and steam resistance. Silicone rubber’s general resilience to heat, steam, and flame damage make it a good material candidate for components in engines, processing plants, and cooking or food preparation industries. The material can be used safely across a wide range of temperatures. When it’s specially formulated for temperature extremes, it can be used at a low of -100° C to up to 250° C.
  • Food-grade materials rating. Silicone rubber seals and component extrusions are ideal for food production and handling. Food-grade silicone is ideal for fabricating cooking tools, conveyance tubing, oven/refrigeration seals and other parts or surfaces used during food production and handling. Because it does not require plasticizers to achieve flexibility, silicones do not impart taste or leach chemicals such as BPA into the food it contacts. Silicones are commonly available in grades consistent with FDA requirements for food contact detailed in 21CFR177.2600 and are available in NSF-51 listed compounds.
  • Good compression set. Silicone materials exhibit a high resistance to compression set after the curing process is complete. As a result, silicones retain consistent mechanical properties over their life.
  • UV resistance.While natural rubber is subject to aging over time due to sunlight exposure, silicone rubber’s silicon-oxygen composition makes it much better suited for prolonged UV exposure. This makes silicone rubber ideal for exterior applications featuring regular or prolonged sunlight exposure.
  • Resilience and rebound. Silicone materials are typically flexible and return to their original form after flexing or bending. The flexibility of the end product will ultimately depend on the hardness rating of the raw silicone material.
  • Strong adhesion to metals. Silicone adheres well to metal materials, such as during molding and extrusion
  • Tensile strength.Silicone rubber’s tensile strength ranges from 200-1,500 psi, depending on the fabrication process and compound formulation. Some grades of silicone rubber can also be stretched to 700% of its original dimensions before cracking or ripping under the tension.
  • Highly inert. Silicone rubber is considered an inert substance, meaning that it doesn’t react with many chemicals or biological elements. Further, it is considered hypoallergenic making an ideal replacement for natural rubber/latex in skin contact and medical applications. Many grades have been testing to requirements detailed in USP Class VI.

Fluorosilicone vs. Silicone

Fluorosilicone is a variant on the silicone polymer with unique characteristics that make it an ideal material for caustic conditions and environments that face temperature and pressure extremes. While both fluorosilicone and silicone are long-lasting and elastic materials, fluorosilicone has greater chemical resistance properties. It can better withstand damage from the following non-polar solvents:

  • Acids
  • Alkaline chemicals
  • Fuels
  • Oils and hydrocarbons

infographic describing the properties of silicone

Fluorosilicones provide longer-lasting EMI/RFI shielding in exterior environments, environments with exposure to chemicals. This makes fluorosilicone ideal for components and seals in the following industries:

  • Aerospace and aviation
  • Automotive
  • Marine

Fluorosilicone is also commonly used for cushioning and static sealing applications, and for tubing to convey non-polar solvents.

Silicone vs. Natural Rubber/Latex

While both silicone and natural rubber are elastomers, their chemical compositions are very different. Unlike silicone’s inorganic silicon-oxygen backbone, rubber has a carbon-carbon bond backbone. Natural rubber is an organic compound, though it can also be synthesized.

Silicone is often considered to be ‘inorganic rubber’ due to many of the shared characteristics between the two materials. However, silicones can be created with a greater range of special properties so industry-specific parts can be customized for long-lasting use in adverse conditions.

Silicone’s superior strengths over natural rubber/latex include:

  • Greater resistance to heat damage.
  • Increased resistance to chemical attacks, corrosion, and degradation from prolonged exposure to caustic and acidic compounds.
  • Greater resistance to damage from fungus and organic buildup because the material itself is inorganic.
  • More resistant to ozone attacks.

Both materials can be used to create EPDM tubing for O-ring fabrication, seals, and more across multiple industries.

Silicone Temperature Ranges

One of silicone’s greatest strengths is its resistance to both heat damage and degradation of elastic properties in low temperatures. Silicone gaskets, for example, can weather temperature extremes of -50° C to 250° C (-60° F to 480° F). Different silicone polymers can be specially created and fabricated to withstand different ranges on this spectrum while retaining or enhancing additional qualities.

How to Protect Sensitive Equipment from Solar Flares

Natural disasters such as hurricanes and wildfires have been causing unimaginable destruction across the country. But there is another phenomenon that has the potential to cause immeasurable damage to modern infrastructure – coronal mass ejections and solar flares.

The sun is millions of kilometres away from the earth – yet disturbances on its volatile surface can push us back into the dark ages.

Solar Flares & Coronal Mass Ejections (CME)

There are super active spots on the sun where the magnetic field is particularly concentrated. Often there are explosions around these regions which result in the ejection of a wide spectrum of radiations running the gamut from visible light to X-rays. These events are known as solar flares and based on their intensity – which is measured on a logarithmic scale – they can either expose air travellers to an increased dose of radiation or wreak havoc on GPS and satellite communication.

While solar flares are to be held in awe – coronal mass ejections (CME), often confused with solar flares are even more potent. They take a while to reach us but the directional blast comprises solar matter particles which cause distortions in the earth’s magnetic field and can cripple electrical grids.

NASA’s Response to Solar Flares and CMEs

NASA has a good idea of the repercussions of solar flares and coronal discharges. In its attempt to “keep the lights on,” it has started the Solar Shield project through which the North American grid system can identify power stations and generators that might be hit the hardest during an event so that pre-emptive and remedial measures can be put in place.

More Solar Flare Mitigation Techniques

NASA is vigilant. But that doesn’t mean all industries can rest easy. A class X behemoth can still cause a lot of damage to ground equipment, especially for military, aviation and sophisticated telecommunication.

Under these circumstances EMI/RFI shielding products prove to be effective. They act as a buffer between items and the coursing electromagnetic currents ensuring the continued operation of sensitive equipment.

Vanguard has been at the forefront of this niche and is capable of supplying EMI/RFI shielding gaskets, manufactured to customer specifications.

The Implications of Air Quality

Air quality is a widely used metric in a variety of portions of our lives. Its composition, particulates, and purity are all of concern for several applications – weather services regularly measure the air in a variety of ways to gather information about our atmospheric conditions and pollution levels; hospitals monitor the quality of the air in patient rooms and “clean rooms”; manufacturing floors for the semiconductor industry are stringently measured for air quality concerns. Even something as inconspicuous as the makeup of the air we breathe can have significant implications for these and other industries.

The measurement process is a complicated procedure, and the accuracy of the measurements is crucial for a successful and useful end result. One problem that often occurs is that, for a number of reasons, the sampling tubing used can cause buildups on the walls of the tubing of the very particulates that are being measured. This can cause some wildly inaccurate readings of air quality, as the ratio of particulate to the volume of air sampled is a critical factor in these readings.

At Vanguard, we have developed some special silicone materials that help in getting accurate readings when used as part of the sampling mechanism, such as in the sampling tubing. These silicone materials have special additives in them to combat the buildup of particulate on the sampling walls through phenomenon such as static buildup. Further, these compounds are made from materials that will not add chemicals or particulate to the airstream, leading to extraordinarily accurate readings.

While it’s easy to ignore the air around us, knowing its properties and being able to regulate them affords us some pretty amazing things – the manufacture of semiconductors in your smartphone, the accuracy of information on your local weather channel, and the preservation of many old or brittle artifacts in museums, to name a few. At Vanguard, we breathe easy knowing we provide one solution in the process for air quality measurement, and have a hand in its many expansive applications.

Vanguard and Hurricane Sandy: Providing Customers with Shelter from the Storm

Vanguard_hurricane_Sandy_Providing_ShelterWhen Hurricane Sandy pile-drove into the New York Metropolitan Area, it didn’t take much for anyone who was caught in it to realize that the night was going to be a long and potentially dangerous one. Unfortunately, those instincts were spot-on. Hurricane Sandy proved to be the worst natural disaster to befall the New York region in nearly a century (the Spanish Flu of 1918-19 being the worst “natural disaster”). Over one hundred people in the Tri-State Area alone lost their lives due to the storm. Hundreds of thousands of homes and businesses suffered damage from flooding and 80 mph winds; many neighborhoods also were decimated by fire. In total, the official tally of damage now amounts to an estimated $71 billion, of which $9 billion is earmarked to improve the storm protection infrastructure of the region in the event of a future disaster of this scale.

Our own facility here in Connecticut lucked out: we suffered no remarkable damage to either our property or production capability. And as many tragedies happened that day, there were an equal number of stories of resistance and resilience in the face of Nature. In fact, many homes and businesses equipped with hurricane shutters and/or floodgate systems came through the disaster in good working order. While many companies should take credit for providing protection for businesses throughout the region, we at Vanguard contributed as well by providing  the gaskets and  seals we extrude here at our facility to several companies that expertly manufacture hurricane and flood protection equipment  used throughout public and private infrastructure to help insure no rain or water creeps (or sweeps) into a building.

Hurricane Sandy was a wake-up call of sorts to New York and the surrounding environs. Hurricanes, as it turns out, are no longer simply the province of Florida, Louisiana, or the Carolinas; they can happen right here in Connecticut and they can be heartbreakingly devastating. Now that the superstorm’s fury has passed, it’s time to insure that our houses, offices, warehouses, factories, and storefronts are secure from any future danger.   Meanwhile, here at Vanguard, we’ll keep working with the manufacturers that produce this high quality protection equipment and providing them with the highest quality sealing products in the industry.

Vanguard: Reporting from the Front Lines of the 4G Revolution

At this moment on Earth, there are approximately 6 billion cell phones in operation. Of these six-odd billion, some 1.2 billion of these phones include mobile web access features. Already the mind goes into overdrive trying to comprehend the bandwidth needed for a wireless network of such dimensions. To cap it all off, with high-speed, digital 4G networks sprouting up overnight (and trans-globally), the wireless capacity of the world is ever more taxed to deliver better, faster, more broad ranging services for an ever-growing number of users.  While many figures in business, politics, and academia devote their careers to tackling the long-term need of increasing capacity, there are others who are caught up in the moment-by-moment race to deliver services at the pace at which they’re demanded.

Vanguard’s Ultra-Vanshield and Microbridge EMI shieldinggaskets are ideal for providing EMI shielding and weather sealing for the base station units that are critical to providing this increased level of service. These base stations are responsible for sorting through the boggling number of wireless operations (anything ranging from speech channels, to transmissions, to pages, to clear reception) occurring at any given moment in the ether.

Base sub-stations – BSS’s – transcode the actions of millions of cell phone users and incorporate them into the greater wireless cellular network. With the level of energy surging through these base sub-stations at any given hour of the day, there’s a matching need to provide protection from both within and without: within, to ensure signal clarity and interference free operation, and without to protect the units from outside unwanted RFI interference while providing substantial weather seal protection—a critical consideration in light of the places where the BSS is physically located, quite often in areas where the climatic elements are brutal, and the units are difficult to service.

At Vanguard Products, we manufacture standard customized, weatheright seals to protect base sub stations from malfunctioning. Our materials and handiwork can be found in BSS systems throughout world  in some of the most punishing outdoor environments you could name. With a reputation for military-grade reliability under all circumstances, our seals will keep your communications systems up and running far into this century.

Vanguard Takes the Lead in Designing N/B/C-Resistant Shielding


vanguard emi shielding gasketsWhen given the acronym “NBC,” most Americans might be forgiven for flashing instantly to the media conglomerate that broadcasts hit shows such as “30 Rock” and the “NBC Nightly News.” But those who are in a certain line of work know an additional meaning for the acronym: “nuclear-biological-chemical.” Defense manufacturers and service-members alike realize the importance of having equipment that is resistant to the deadliest hazards of the modern battlefield.

EMI shielding is a must for military electronics in general, and insuring that the EMI shielding will perform its job in even the harshest (and most unfortunate) circumstances is one of the necessities of 21stcentury warfare. If, Heaven forbid, a tactical nuclear device were actually to be used against American forces, there would be the need for EMI shielding gasketsthat are not only proof against the blast radiation itself, but are also resistant to the powerful cleaning agents used on vehicles and equipment that have been subjected to that level of aggression.

Vanguard Products is fully capable of manufacturing such N/B/C-resistant EMI shielding gaskets. We account for everything from biological warfare to jet fuel spillage when we design our ITAR-certified custom shielding. The fact is our troops go into battle with some of the most advanced technology the world has ever seen, and that technology comes with highly specific requirements for remaining effective in the worst of conditions.
