Viton gasket material is an incredibly durable material for seals, gaskets, o-rings and more. All of which can custom manufactured to your specific requirements. We can custom cut to any size and shape you need.

Or you can purchase off the shelf Viton rubber sheets that we offer for sale below.

Viton rubber is a high-performance rubber that has an excellent resistance to many acids, chlorinated fuels, and hydrocarbons.

Specific gasket sheet properties should be taken into account before use in the gas and oil industry. These properties include hardness, thickness, and temperature resistance of the rubber. Here are some of the general properties that should be considered before use in any industrial application. Viton gasket sheet rubber is probably one of the few high-performance yet durable rubber materials you will come across.

Viton Gasket Sheet Technical Specifications

Viton is one brand of the FKM (fluoro-elastomer) rubber and it is so popular that the brand name has gradually become synonymous with the fluoro-elastomer material, hence many people will often compare Viton to fluoro-elastomer. With this in mind, it is equally important to note that this rugged rubber is perfectly suited for the applications that need hard-wearing seals, gaskets, and O-rings.

Viton is the trade name used for most fluorocarbon elastomers (FKM). These materials have been found to exhibit great resistance to high temperature as well as low compression set. They have been found to respond well with resistance to high temperatures, ozone, mineral oil, oxygen, fuels, synthetic hydraulic fluids, and aromatics among many other organic chemicals and solvents over a temperature range of -25 degrees Fahrenheit to +400 degrees Fahrenheit.

The material’s low-temperature resistance abilities for static applications is limited to about -40 degrees Fahrenheit under a more specific formulation.

However, under dynamic conditions, the material’s lowest service temperature is between 5 degrees Fahrenheit to 0 degrees Fahrenheit.

The gas permeability of Viton is very low and almost comparable to that of butyl rubber. A specific formulation of this gasket material could improve its resistance to acids, steam, water, and fuels. Here is a breakdown of the rubber gasket technical specifications.

• Durometer (Shore A) 75+/-5

• Elongation 165% minimum

• Fluorine content 66% minimum Fluorine content

• Tensile strength 1200 PSI minimum

• Color – Black

• Temperature range -20 degrees Celsius to +350 degrees Celsius

• Thickness range 1/64” to 1” in slab or roll form

• Surface finish fabric, smooth paper, or plate finish

General Properties of FKM Viton Sheets

• Chemical Resistance: Viton offers a broad range of resistance to fuels, lubricants, oils, and a majority of mineral oils. It also offers good resistance to most aliphatic hydrocarbon fluids which act as solvents for many rubber materials.

• Compression Set: The gasket material offers exceptionally good resistance even at temperatures that appear to stiffen many other non-fluorinated elastomers.

• Environment: Viton also offers good resistance to atmospheric oxidation, weather, and sun as well as strong resistance to mold and fungus.

• Thickness and tolerance: Viton sheets usually comes in thickness of between 1mm and 3mm. In some applications, however, Viton thickness is close to 10mm.

• Temperature range: The Viton is able to operate at extremely low and high temperatures, able to withstand temperatures as low as -20 degrees Celsius up to +350 degrees Celsius. It is because of its temperature range that this material is thought to be a highly resilient material.

What is Viton Used For?

Due to its excellent chemical and temperature resistance, the rubber sheets are used in a wide range of industries and applications. It is, however, often used in the mining, chemical processing, power generation, pharmaceutical, food and beverage, and aerospace industries.

Viton gaskets tubing is popularly used in automotive as well as other fuel transportation applications that involve high concentrations of biodiesel. The type F and type B Viton rubber materials have been found to be more resistant to acidic biodiesel since this fuel is highly oxidizing and unstable.

Some of the most common applications of Viton rubber include:

• Expansion Joints

• Joining sleeves and chemical transfer

• Flange gaskets for containers, tanks, and pipes.

• The lining of tanks or containers storing oils, chemicals, petrol, diesel, or other types of aggressive agents

• Isolation barriers

• Sealing and insulation strips

• Chemical proof flashing

Advantages of Viton Gasket Material

Compared to many other elastomers in its grade, Viton is far much better able to withstand high temperature without compromising its excellent mechanical properties. Besides, its oil and chemical resistance capabilities are not affected by extremely high temperatures.

Compounds that makeup Viton tend to remain substantially elastic even when exposed to laboratory air oven reaching 204 degrees Celsius or even to intermittent exposures of close to 316 degrees Celsius.

Viton grades have also been found to resist degradation from a vast array of fluids and chemicals including lubricants, fuels, oils, and a majority of mineral acids as compared to other non-fluorinated elastomers. Simply put, this implies that Viton offers the best fluid resistance for the standard commercial rubber. And with its low permeability to a wide range of chemicals. Viton delivers incredibly good performance when it comes to oxygenated automotive fuels.

The advantages of Viton do not stop there since this material also displays good resistance to compression even at extremely high temperatures that would render many other non-fluorinated elastomers brittle.

Viton is also particularly resistant to atmospheric oxidation, mold, fungus, climatic conditions, and the sun.

Finally, Viton gasket material has excellent electrical properties (in low frequency and low voltage applications) and low burning attributes.

Before buying any Viton gaskets, it is important to note that there are numerous grades of this rubber material and it is, therefore, crucial to understand all the requirements of your application to make sure the appropriate grade is put to application.

All in all Viton can withstand exposure to a wide range of aggressive gases and chemicals as well as the rigors of down-hole operations.
