What is Viton rubber O ring?
Viton™ is a fluoropolymer elastomer and synthetic rubber compound, trademarked by DuPont under this brand name. The standard grade for Viton™ is A grade, which has 66 percent fluorine content and is most commonly used in o rings and seals.
Are Viton o rings better?
Crucial Differences 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℉.
What is the difference between Viton and nitrile 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.
How long do Viton o rings last?
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. Buna is effective to 250°F.
What is the difference between silicone and fluorosilicone?
Fluorosilicone is a variation of silicone rubber that maintains excellent high temperature stability and mechanical properties, while offering greater resistance to fuel, oil and other chemicals. These added benefits also come with a cost—fluorosilicone is typically five times the cost of silicone.
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.
Are Viton O rings black?
This O-ring is made of black Viton and has a durometer of 90A, a round cross-section, and can be used across a wide temperature range (-15 degrees F /-26 degrees C to 400 degrees F/ 205 degrees C)….

Is fluorosilicone conductive?
Fluorosilicone – Fluorosilicone Sponge, Solid Fluorosilicone, Electrically Conductive Fluorosilicone. Fluorosilicone (FVMQ) is fluorinated version of silicone which gives this polymer superior chemical resistance.
What are the different types of O-rings?
Different types of O-ring applications Nitrile O-rings. Widely regarded as a general-purpose type of O-ring, Nitrile elastomers (also known as Buna-N or NBR) offer a respectable temperature range of between -50°C and 120°C, with excellent Silicone O-rings. Viton. FEP O-rings. PFA O-rings. USP Class VI O-rings. Vulc O-rings. Large O-rings.
What are the uses of silicone o-rings?
Silicone O-rings are round, highly temperature resistant devices that seal connecting pieces in machinery where flexibility and longevity are important. These O-rings are resistant to UV damage, corrosion, oils, chemicals and solvents. They are used for electrical insulation and are dielectrically stable.
What is about silicone o-rings?
Resistant to: extreme temperatures,fungal growth,UV and ozone exposure,and weathering
