WHY BUY VITON SEALS?

• Viton and other seals have several very crucial differences that make them especially well suited to certain applications. While both Viton and other seals both serve as great sealing options at moderate temperatures, Viton is far superior to other seals for high temperature applications. 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. Valve seals made of non-Viton materials, such as Poly, are only effective up to 250°F.

• These are brand new production seals. Viton has good flexibility like Nitrile, which means it can handle some runout between the valve stem and guide. It is also considered to be a more durable material than silicone. Viton also has better wear resistance than most other seal materials, making it a good choice for applications where long term durability is a must.

• Viton seals provide less friction as well, due to 5% Teflon.

• We also have these for most other engines if needed, so check out our other listings
