Our guides are made from Silicone Manganese Bronze in a USA machine shop. This material dissipates heat the fastest and is a very durable metal to use as a guide. The guides may have to be reamed or honed according to the tolerance that you want to run on your valve stems. Our guides also have a threaded top to prevent metal clad seals from slipping or being pushed off, which is a problem when changing from the OE style hat seals to an aftermarket metal clad seal.

NOTE: You must check the size of your valve guide(s) prior to ordering to make sure you receive the correct fit! The guides may have to be reamed or honed according to the tolerance that you want to run on your valve stems.

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
