Oil seals are one of the major contact type sealing devices.
• They prevent leakage of the lubricant or other sealed substance, and
• prevent entry of dust and foreign matter (dirt, water, metal powder, etc.) from outside.
It is possible to get custom-made seals manufactured at reasonable rates from good-quality manufacturers if the readymade seal specification doesn’t meet the requirement.
First, an elastomer, most often nitrile, is vulcanised to a metal ring. This creates a stiffening effect that includes a specialised metal tension spring directly behind the sealing lip, keeping the oil seal firmly in place against the moving part.

The piston oil seal is located between the piston and the cylinder wall. Its main function is to seal the combustion chamber and prevent oil from leaking into the combustion area. This is essential for maintaining proper lubrication of the piston and preventing damage due to overheating and friction.
