Is Viton rubber heat resistant?
Viton is the choice over Buna for high-temperature applications. Viton seals hold indefinitely at temperatures up to 400°F and can last up to 48 hours at temperatures up to 600°F.
What temperature can O rings withstand?
The general accepted range for o-ring use is approximately -75 degrees and 620 degrees Fahrenheit. This wide spectrum is due to the materials from which o-rings can be manufactured.
What is Viton seal?
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.
Are O rings heat resistant?
Why silicone O-rings (VMQ)? Excellent resistance to extreme temperatures -50°C to + 232°C (-58°F to +450°F). Some special compounds resist even higher temperatures. Retention of properties of silicone at high temperature is superior to most other elastic materials.
Is Viton better than nitrile?
General Suitability: Viton® is best suited for diverse sealing jobs that require high temperature and chemical resistance. 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.
What Viton 90?
Viton® 90 O-Rings Viton® (FPM, FKM, Fluorel®) resist mineral oils and greases, aliphatic, aromatic and also special chlorinated hydrocarbons, petrol, diesel fuels, silicone oils and greases. It is suitable for high vacuum applications.
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.
Are rubber o-rings fuel 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 fuel proof?
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.
What is the difference between Nitrile and Viton O rings?
Temperature: Viton® seals can withstand temperatures up between -20°C to 210°C. 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.
Are rubber O rings fuel resistant?
Are Viton O-rings black?
This Viton O-ring is black in color, round in shape, has a durometer (hardness) of 75A, and is designed for use in a wide variety of sealing applications. Viton has excellent heat, fuel, and chemical resistance.
