Oil seal materials
The 22% oil seal is another commonly used size that offers similar benefits to the 12% seal. This seal is often found in industrial machinery, such as pumps, compressors, and generators, where it plays a crucial role in maintaining the integrity of the equipment. The 22% oil seal is designed to withstand high pressures and temperatures, making it ideal for use in demanding environments where reliability is paramount■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.
The major cause of extrusion and nibbling is stress caused by high pressure. This is commonly noticed when the oil seal has a chipped or nibbled look. In fact, in some cases, the surface of the seal tends to peel on its own, which makes it have a shaved look. What the stress does is that it increases the clearance gap between the mating edges, which causes the seal to get entrapped, and then leads to severe physical damage.
Most oil seals are designed to support very low-pressure (8 psi or less) applications. If at all, there will be additional pressure along the way, pressure relief should be put into play. This is why it’s important to know the characteristics of the oil seals you are considering and compare them with your application.
