PK 2

Piston seal PK 2



is a double-acting polyurethane piston seal designed for pneumatic cylinders and can also be used for pneumatic valves if overall dimensions permit.

Advantages


- Rounding in the centre of the dynamic cutting edge reduces friction and improves smoothness of movement.
- In addition, the advantageous economical build-up reduces machining times.
- Excellent performance even at low pressures.
- Compensates well for slight radial piston deviations.

The special seal shape allows for easier installation, high adaptability and good function even at low pressures.
