What is a Viton gasket?

What is a Viton gasket?

Viton® gaskets are made of high-performance fluoroelastomers that provide outstanding resistance to heat. These rubber gaskets generally support temperatures from 15° F to 400° F and are suitable for applications that reach 500° F intermittently. Gaskets made of Viton® also provide excellent resistance to: oils.

Is Viton A rubber?

Viton® is a brand name of DuPont for its synthetic rubber and fluoropolymer elastomer, commonly used in O-rings and other moulded or extruded products.

Is Viton rubber heat resistant?

Viton® has outstanding resistance to heat. In fact, one Viton® o-ring can withstand temperature ranges from -13°F to 446°F. Since some rubber compounds are known to fail in extreme high-temperature environments, Viton® is a great candidate for applications working under these circumstances.

What is a FKM gasket?

FKM rubber gaskets are made of fluoroelastomer, a synthetic rubber that is known for its hard wearing properties. The material is used for O-rings, seals, gloves and most importantly for this blog post, FKM is used for gaskets. Industry Standard.

Which is better PTFE or Viton?

Viton vs Teflon (PTFE) – Viton offers a greater temperature resistance but falls short of Teflons(PTFE) chemical resistance. Also, Teflon is slightly less thermally resistant but offers much more in the way of non-adhesive properties.

What is Viton good for?

An exceptionally broad range of chemical resistances make Viton seals a perfect option for most applications involving oils, fuels, and mineral acids, and these seals also boast excellent resistances to oxidation, ozone, UV exposure, weather, fungus, and mold.

How long do Viton gaskets last?

O-Ring Shelf Life Recommendation per AS5316

What temperature does Viton melt?

Viton™ Curative No.

Melting Point 80 °C (176 °F) min.

What temperature can Viton withstand?

Viton seals provide an indefinite seal for temperatures up to 400°F, and for temperatures up to 600°F they offer an excellent seal for more than 48 hours. Buna on the other hand is only effective up to 250°F.

Is FKM and Viton the same?

These rubber compounds give exceptional heat resistance with compatibility across many fluids or chemical exposures. The most commonly known name for these compounds is “Viton,”™ which has become the generic name for all FKM polymers and rubber compounds.

Is FKM same as PTFE?

FKM offers greater temperature resistance but falls short of PTFE’s properties in terms of chemical resistance. While PTFE is slightly less thermally resistant but offers much in the way of non-adhesive properties. It’s a dead heat!

What is Viton seal good for?

O-rings and other static seals made from Viton™ fluoroelastomers are widely used in aerospace, military, chemical processing, oil and gas, and other application areas with extreme temperature, pressure, and chemical environments.

Is Viton A rubber or plastic?

As mentioned, Viton is DuPont’s (now Chemours) brand name for fluorocarbon rubber. This is a synthetic rubber and fluoropolymer elastomer and is commonly used for O-rings and other molded or extruded parts.

Which is better Viton or silicone?

Both materials are well suited for use in the -30 to 205°C range. Silicone has an advantage in lower temperatures and Silicone has an advantage in higher temperatures. Marco offers specific compound formulations extending these ranges even futher as can be seen in the following compound comparison chart.

Is PTFE better than Viton?

Oil Resistance: Poor
Viton vs Teflon (PTFE) – Viton offers a greater temperature resistance but falls short of Teflons(PTFE) chemical resistance. Also, Teflon is slightly less thermally resistant but offers much more in the way of non-adhesive properties.

Are there different grades of Viton?

There are four major families of Viton™ fluoroelastomers: A, B, F, and ETP, each with its own unique performance characteristics.

Which is better Viton or PTFE?

Is nitrile better than Viton?

Environmental Properties: Viton® O-rings and seals have a wide range of chemical resistance (involving mineral acids, fuels, and oils) and this material is also highly resistant to oxidation, UV exposure, fungus, weather, ozone, and mould. This makes Viton® far superior to Nitrile in these regards.

What is difference between Viton and FKM?

All in a name
Fluoro-Elastomer is usually referred to as FKM FPM or as VITON™ after the popular brand which produces it. You may see this rubber listed in different places with these different names, but they are all one and the same.

What is Viton not compatible with?

Do not use Viton with acetone, esters, amines, organic acids, acetic acid, MEK, ethyl acetate, highly polar chemicals, etc. Viton is generally serviceable in dynamic applications to temperatures of -18 to -23 °C.

Is PTFE the same as Viton?

Is Viton the same as Teflon?

What is the difference between Viton A and B?

Viton® B has better resistance and retains flexibility better after dry heat aging than Viton® A. It is recommended with good mechanical properties. Viton® B is specified by the Fluid Sealing Association to resist sulfur dioxide in power generating factory systems.

How do I identify my Viton?

However, by looking at the material, we can identify Viton by its appearance of green-brown colour where nitrile rubber has a yellow colour.

What color is Viton?
