Different Types of Oil Seals
Metal O.D. wall
(with a reinforcing inner metal case)
Broad chemical resistance, except against liquid alkaline metals and fluorine gas under pressure. Good sliding qualities, low wear and tear. Temperature range from -200 °C to +260°C. PTFE has hardness of approximately 95 °Shore and installing these O-rings in split grooves is recommended or alternatively the use slit or sheathed types due to the low elasticity.

In conclusion, the piston oil seal is a critical component in an internal combustion engine. It plays a vital role in preventing oil leakage, reducing friction, and ensuring efficient engine operation. Regular inspection and maintenance of the piston oil seal are essential for maintaining the performance and longevity of the engine.
