Oil seals come in a wide range of types, and they also have various sizes.
When selecting the right oil seal for your machine from among these many varied types of oil seals, the following two criteria are very important.
However, rubber-cased seals do have limitations. For example, during installation, shear stresses can build up between the seal and housing wall, causing the seal to release itself.
■Anti-wear agents: Anti-wear agents help protect parts of the engine that are especially susceptible to damage from high temperatures, like cylinder walls, lifters, cams, and piston rings. This additive acts as a protective layer around these components to limit friction in metal-on-metal situations.
