Choosing the right oil seal
This tough, chemically inert polymer has a wide working scope as well as:

black spark plug. This increased durability can result in fewer maintenance issues and a more reliable engine overall.

Friction damper
Due to having a higher density, Viton has the widest temperature range of -40°F to over 400°F (-40°C to over 240°C) making it a perfect choice for higher temperature applications. Viton® also has the largest range of chemical resistance, i.e., it is resistant to silicone oil and grease, mineral/vegetable oil and grease, aliphatic, aromatic, and chlorinated hydrocarbons, non-flammable hydraulic fuels as well methanol fuels, and more.
When installed, the oil seal’s flexible lip is placed against the rotating shaft, and the casing is pushed into the housing for support. It is crucial that the sealing lip is lubricated to avoid overheating caused by friction.
■Rust and corrosion inhibitors: Your engine’s internal parts can rust and corrode when exposed to acids and moisture. These additives create a protective film over your engine’s internal parts to help prevent such damage.
