The double effect PSZ seal is the result of a combination between plastic runner with step cut and elastomeric Q-ring (NBR) for energizing. The high strength of the plastic material, grant the sealing effect at high pressure and permit higher radial clearance (Piston/ Bore) compare to other piston sealsK 17 is a two piece double acting piston seal which consists of one special mixture PTFE profile ring and an o-ring as energizing element.

• Easier machining of the piston

• The strength of the plastic grants high pressure

• Long service life

• High sliding speed

• Easy installation

• Wide range of dimensions
