A piston oil seal, also known as a piston seal ring, is a critical component in an internal combustion engine. It plays a crucial role in preventing oil leakage from the piston and ensuring efficient engine operation.
6. Ensure that the oil seal solidifies
In this kind of seal, wider tolerances are possible between the OD of the seal and the seal housing. Irregularities of the housing surface can be taken up by the resilient rubber layer on the outside of the seal. However, the rubber covered seal can be blown out under high pressure in a reciprocating application whereas, with a metal case, there is no such danger.
