Is Viton better than Nitrile?

Is Viton better than Nitrile?

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 the difference between Viton and EPDM?

Viton® rubber is a fluoro elastomer, whereas epdm rubber is ethylene-propylene-diene-monomer. The primary differences between Viton® and EPDM is in their chemical resistance and temperature ranges. Both have different properties and applications for general industrial use.

What is Viton used for?

A Viton™ seal is simply a seal manufactured from Viton™. These seals or gaskets are commonly used to seal leaks, valves, pumps and similar. Viton™ o rings are the most common type of seal, which we provide here at NES in a variety of sizes and profiles.

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.

Are Viton O-rings better?

While both materials are suitable for moderate temperature applications, Viton® is the superior choice for high temperatures. Viton® standard compounds can withstand temperatures up to 446℉, while Buna o-rings can only handle up to 257℉.

How long do Viton O-rings last?

O-Ring Shelf Life Recommendation per AS5316

How strong is Viton?

High temperatures: Viton O-rings withstand temperatures from -20°C to 210°C (-4°F to 410°F). Chemicals: Viton can withstand a wide range of chemicals: these include oils, acids, silicone fluids, and gasses, as well as halogenated and aromatic hydrocarbons.
