Piston Seals

Piston Seals or Piston Rings provide a seal between a piston and the cylinder bore.

This seal prevents leakage past a piston and seals the system’s pressure from either one direction (single-acting) or from either direction (double-acting), allowing the cylinder to extend and retract.
