Function
The KK 22 compact seal is a double-acting seal consisting of a sealing ring and guide rings. The KK 22 guarantees a good sealing function – also in low pressure areas. Due to the integrated guide elements, the piston length can be reduced to save material.

Installation
The KK 22 can easily be installed on one-piece pistons.

Remarks
Due to the NBR impregnated fabric on the contact surface, the KK 22 has an increased wear resistance, an improved gap extrusion resistance and minimisation of friction.
