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.
Swan Seals design and create a comprehensive range of Piston Seals, Piston Rings and U-Seals for a multitude of applications, used across all industries. Seals can be manufactured in various sizes and materials, for solid and split pistons, single or doubling-acting.
