 Are valve seals rubber?

 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.

FAQ:

1. What are the benefits of the FKM rubber?

* Wide range of temperature from -15 degree to 200 degree.

* Excellent in chemical and oil resistance

* Good adhesion to metals

     2. Could you pls introduce more details of the FKM rubber?

The resistant chemicals of the FKM are including: Mineral oil and grease, ASTM oil No.1, IRM 902, IRM 903 oils and etc; Silicone oil and grease; Gasoline; high alcohol content; Mineral and vegetable oil and grease; high vacuum; Aromatic hydrocarbons(benzene,toluene); Kerosene;Hydraulic oil; Lubricating and fuel oils; Very good ozone,weather and aging (sunlight)resistance. FKM rubber has good adhesion to metals so we usually use it to produce Valve stem seals and oil seals.
