Are valve seals rubber?

Valve stem seals are crafted from a number of substances, which include nylon, PTFE rubber, steel, and artificial rubber.

Sometimes those substances are mixed right into a unmarried state-of-the-art design. When artificial rubber is used, there are 3 fundamental types: nitrile, polyacrylate, and FKM®. The largest distinction among the 3 styles of artificial rubber seals is their warmness resistance. A artificial rubber seal with inadequate warmness resistance will harden and crack prematurely. This can cause seal degradation, with portions of the seal breaking away and clogging the oiling gadget and oil pickup screen, inflicting engine harm from lack of lubrication. Because of this, many NAPA valve stem seals for overdue version vehicles are fabricated from FKM®. FKM® is the nice fabric presently to be had to be used in lots of today’s hotter-strolling engines, especially the smaller home and imported models. It is regularly mixed with a “metallic jacket” or overlaying that completely surrounds the FKM® high-quality seal. FKM® gives tremendous resistance to each warmness (as much as 450° F) and abrasion, and is the selected fabric for maximum Fel-Pro valve stem seals.
