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.\u003c\/p\u003e\u003cp\u003eThese 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.\u003c\/p\u003e\u003cp\u003eViton seals provide less friction as well, due to 5% Teflon.\u003c\/p\u003e\u003cp\u003eWe also have these for most other Motorcycle engines if needed, so check out our other listings.\u003c\/p\u003e\u003cp\u003eThese parts are brand new production!!!\u003c\/p\u003e\u003cp\u003eThe terms Ironhead, Sportster and Harley® are for descriptive purposes only.
