Piston Seals

Piston Seals or Piston Rings

These are used in hydraulic cylinders for fluid sealing. They are internal to the cylinder head and seal against the cylinder bore,therefore 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.

Turcon Glydring

Double acting o-ring energized piston seal for dynamic applications. Provides low friction with no stick-slip, hence minimal break out force and high wear resistance. Applicationof these piston seals in actuator cylinders.

Turcon Glydring T

All the same benefits of the standard Glydring, but shows improved leakage control and better resistance to extrusion. Installed in grooves to ISO 7425.

Zurcon Glydring P

Double-acting Zurcon Glydring is a combination of Zurcon based material slipper seal with a step cut and energizing rectangular elastomeric ring. Two times bigger extrusion gaps are possible due to Zurcon high strength plastic material. The step cut enables installation into closed grooves and aids flexibility due to the stiffness of the material.
