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.
Application Industry
- Improper use of sealants.
- Radial lip seals are the most common type of oil seal used to prevent leakage of fluids such as oil or grease in rotating machinery. They consist of a metal outer casing with an elastomeric sealing lip that is pressed against the shaft to create a tight seal.

6 GUIDELINES TO FOLLOW WHEN CHOOSING AN OIL SEAL




Oil seals are used in a great many machines.
Oil Seal Installation: A How To
Why is mechanical seal important in this situation? It is because the rotating shaft has to move in a wet environment, but there should not be the leakage of pressurized fluid. Hence, the role of a seal is quite critical.
In this blog, we attempt to highlight what are Oil Seals and the various Rotary Shaft Seals including Mechanical Face Seals, Water Pump Seals, Gland Packings, and V-Seals that are readily available.
