K501 Hydraulic piston seals
K501 piston seal consists of «Z» cut thermoplastic sealing ring and rectangular shaped elastomer energizer ring. It has good sealing even at low pressures thanks to the rectangular formed elastomer.
The «Z» cut ring provides a superior sealing without losing the contact with the tube surface at high and shock pressures. The ring can work at higher extrusion gaps in comparison with PTFE material and has high strength and wear resistance thanks to the glass filled thermoplastic material.
Advantages
- Designed for grooves according to ISO 7425/1
- Easy fit without installation tool
- Simple one piece piston head with small groove
- Higher extrusion gap in comparison with PTFE and PU piston seals
- High wear resistance, long service life
- Outstanding resistance to pressure shocks
- Operating in heavy duty conditions
