- Oil seals are typically made from a variety of materials, including rubber,PTFE (polytetrafluoroethylene), and various metals. Each material offers unique benefits depending on the specific application and operating conditions. For instance, rubber oil seals are well-suited for applications that require flexibility and resistance to high temperatures, while PTFE seals are renowned for their chemical resistance and low friction properties.

PTFE, which is used in the well-known brand Teflon®, is less commonly used, but it is the preferred material for specific rotating seals in the chemical, food and pharmaceutical industries. This material is notable for having a very low frictional resistance and the best chemical resistance. It can also withstand a very wide range of temperatures in these types of seals; -80 ˚C to 200 ˚C. The shafts on which oil seals with PTFE lips are used require a harder and finer finish. Something like an axle sleeve can also be used to meet this requirement.


Oil lip seals play a significant role in several industrial applications to avoid intermixing fluids and prevent contaminants and moisture from affecting the bearings. With such a vital role to play, it is essential to choose the right material for these seals. The choice of the material will depend on factors like the type of fluid being sealed, operating temperature, pressure, and compatibility with the operating environment. The following list of materials is typical for making oil lip seals:

Similar to the housing surface stop technique, this method uses a stop at the machined housing face to set the seal depth. It is typically used in housings with flat outer surfaces. Verifying the placement through visual inspection or with a feeler gauge ensures placement accuracy.
