Hydraulic Piston Seals For Hydraulic Cylinders
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.

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.
A hydraulic piston seal or piston ring is usually manufactured in our Turcon® Polytetrafluoroethylene (PTFE) based material or Zurcon® polyurethane . Specially engineered for fluid power applications, these compounds provide exceptional resistance to wear and outstanding extrusion properties. Compatible with virtually all media, they demonstrate unrivalled performance at extremes of temperature.
