PK 1
Piston seal PK 1
is a classic single-acting piston seal. For use in a double-acting cylinder, two PK 1 cuffs are used "back to back". The suitable profiles and the high elasticity of the material make it easy to fit the seals even in closed grooves.
Advantages
- Low friction
- Rounding of the dynamic cutting edge improves smoothness of movement
- Excellent performance even at low pressures
These advantages are provided by the deeper groove between the static and dynamic cutting edge, together with the rounding of the cutting edge.
