Oil seals applications
Start the engine and check for oil leaks round the sump flange. Stop the engine and tighten the mountings.



It is important to choose the right type of oil seal for a given application, as it may need to address specific operational concerns such as:
Hydrogenated nitrile rubber (HNBR)
Samples Submission :21-28 days with existing toolings.


A wide range of sealing devices are used in various machines.
Sealing devices serve the following functions:
Oil seals work by squeezing and retaining lubricant in a thin layer between the lip and the shaft. Perfect sealing is ensured by the hydrodynamic action of the rotating shaft, which in turn produces a slight pump action.

Elring supplies liquid sealants, head gaskets and also oil seals. The extensive range almost always offers a solution for an engine block and quality is can’t be missed in Elring's product range.
All are fitted with a spring to preload the sealing lip. All these types are for non-pressurised or low-pressure applications up to 0.5 bar for diameters of a limited size. For diameter of 500 mm or more, the maximum pressure is 0.1 bar. For higher pressures, special types or PTFE lip seals can be used.
