While both Viton and Buna seals both serve as great sealing options at moderate temperatures, Viton is far superior to Buna for high temperature applications. O-ring seals are a round cross sectioned sealing device available in a variety of materials (elastomers) and standard AS568A, metric and Japanese Industrial Standard (JIS) sizes. Standard Viton®/FKM compounds can provide continuous sealing at temperatures up to approximately +205°C. On the morning of the eighth day, some say the first thing He did was create PTFE! (Actually, it was a gentlemen named Roy Plunkett who created PTFE in 1938 while he was working at DuPont. "It's easy to claim your using what you say you are, but much harder to prove it. Specify and ask for Viton®. Gasket material is a soft and conformable material that is ideal for applications with limited bolt load torque available. Some classes of materials that are suitable for o-rings for vacuum service include Nitrile (Buna-N), Fluorocarbon (Viton), Ethylene Propylene (EDPM), Perfluoroelastomer (FFKM, Kalrez) and silicone rubbers. KALREZ@ perfluoroelastomer parts combine the elastomeric properties of VITON" fluoroelastomer with the chemical resistance of TEFLON@ fluorocarbon resins. With extensive chemical compatibility spanning a wide range of concentration and temperature ranges, fluorocarbon elastomers have gained acceptance in a variety of applications.

As new chemicals and fuels are developed, new technology in Viton ™ has led to the development of the Viton ™ F family of sealing products. Both offer excellent compression set and have a wide range of uses in industrial and domestic applications. Viton ™ F - 70% Fluorine Best-Chemical Resistance. It is not Viton. To fit RTJ flanges, we offer CE and LE grade phenolic and glass filled Teflon. Rubber Cord is available on our on-line shop in the following materials; Nitrile (NBR), FKM (Viton), EPDM, Silicone 60sh (various colours) silicone sponge and neoprene sponge rubber cord.
