3. Pressure Maintenance In many applications, oil seals are designed to maintain pressure within a system. By preventing the exit of oil and the entrance of contaminants, they help in sustaining the necessary pressure levels for optimal operation. This function is especially important in hydraulic systems, where pressure plays a critical role in performance.
what is the function of oil seal

The primary seal, often made of polyurethane, rubber, or PTFE (Teflon), prevents fluid from leaking past the piston. The secondary seal, typically an O-ring, provides additional security against fluid bypass. Wear rings, usually made of hard materials like bronze or steel, reduce friction and prevent scoring of the cylinder wall.
