Q. What is the purpose of Nitrile Oil Seal?

Answer

The purpose of the Nitrile oil seals is to stop the fluid from leaking between the shaft and housing. The metal case used in its making provides rigidity and strength to the seal while it is being held in the bore or recessed groove. Moreover, the garter spring ensures constant pressure and maintains the radial force to the shaft, flattening the sealing edge to a defined width.
