Product detailed description
The K501 piston seal consists of a «Z»-cut thermoplastic sealing ring and a rectangular elastomer energizer ring. It provides good sealing even at low pressures thanks to the rectangular elastomer. The «Z»-cut sealing ring provides excellent sealing without losing contact with the tube surface even at high and shock pressures. Compared with PTFE, the ring can work with larger extrusion gaps and offers high strength and wear resistance thanks to the glass-filled thermoplastic material.
Advantages
- Designed for grooves according to ISO 7425/1
- Easy installation without an installation tool
- Simple one-piece piston head with a small groove
- Larger permissible gap compared with PTFE and PU piston seals
- High wear resistance, long service life
- Excellent resistance to pressure peaks
- Operation in demanding conditions
Applications
- Construction machinery
- Forklift trucks
- Heavy-duty cylinders
Also searched as: piston seal, piston U-cup, hydraulic seal, hydraulic cylinder seal, NBR, nitrile, Kastas, K501, Kastas K501, PA, Kastas PA.
