Hydraulic Piston Seals

Trelleborg Sealing Solutions offers a wide range of piston seals that provide the ultimate in leakage control. Our proprietary piston seal designs meet users’ requirements for low friction, compact form and simple installation.

Piston Seals or Piston Rings are used in hydraulic cylinders for fluid sealing. They are internal to the cylinder head and seal against the cylinder bore, preventing fluid from flowing across the cylinder head. This allows pressure build up on one side of the piston, making the cylinder extend or retract.
