Are Viton o rings gasoline resistant?

This material has an excellent tolerance for high temperatures, resistance to oils, fuels and hydraulic fluids as well as aromatics and solvents. … As well as resisting oils, petrol and hydrocarbons, Viton™ is resistant to mineral acids, halogenated hydrocarbons and more.

Is Viton gasoline proof?

With exceptional chemical resistance, Viton® offers swell resistance in high octane and oxygenated fuel blends. This gives Viton® superior performance abilities in Ethanol/Methanol blended gasoline applications.

What O ring material is resistant to gasoline?

Buna (Nitrile or NBR) O-rings: general purpose sealing



Buna O-rings, also known as nitrile or NBR O-rings, offer excellent sealing and mechanical properties at a low cost. Buna O-rings have resistance to common lubricants and are recommended for crude oil, gasoline, propane, petroleum oils and water.

Are O rings petrol resistant?

Nitrile o-rings are a popular type of rubber seal gasket that’s used in a wide range of applications and environments – they’re broadly seen as a general-purpose o-ring type, with reasonably resistant sealing properties against water, gasoline, petroleum oils, crude oil, propane and some hydraulic fluids.

Is Viton harder than nitrile?

Viton® seals are prone to failure below -15°C in dynamic applications, as they become inflexible and hard. … This makes Viton® far superior to Nitrile in these regards. They are also designed to resist most oils and lubricants, more importantly petroleum-based lubricants.

IMPORTANT TO KNOW:  Who has the highest oil well?

How long do Viton o rings last?
