Oil seals applications
- When selecting a rubber pipe gasket, it is essential to consider the material composition, size, and compatibility with the specific type of pipe or fitting being used. Different rubber compounds offer varying levels of resistance to chemicals, temperature, and pressure, so choosing the right gasket for the job is crucial to ensure a leak-free connection.
- 3. Compression set Compression set is the permanent deformation that occurs when a material is subjected to constant pressure over a period of time. High temperature rubber gaskets have low compression set, which ensures that they maintain their shape and seal effectively over time.

Oil seals applications
Most standard oil seals have to comply with the DIN 3760 and ISO 6194 standards. Different standard types of oil seals are available that comply with these requirements.
It is quite common for a groove to develop at the sealing lip at some point due to long-term use. As a result, the new oil seal no longer fits and seals properly. It is not strictly necessary to replace or repair the entire shaft. Take a closer look at the dimensions first. It may be possible to fit with a slightly narrower or wider oil seal next to the groove. Alternatively, using the Speedi-Sleeve repair kit, repair the running surface under the seal.
Installation of the oil seal


Old School O-Rings
Most oil seals consist of some basic elements that configure their structure, such as the sealing element, the metal case, and the spring:
These types are made with a metal outer case and a PTFE lip. They are suitable for a wide range of temperatures from -90 °C to +260 °C.These lip seals can also be used for higher pressures of up to 10 bar (special types up to 25 bar) and rotational speeds of up to 40-45 m/s. Certain grades of PTFE are suitable for use in pharmaceutical and food applications. One important point is that PTFE lip seals do require a shaft with a harder, smoother finish.
