Piston seal 85x69.5x6.3 PSZ
Product Code:: PSZ 0850 0695 063 RN
PSZ/A127 TYPE PISTON SEAL
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 seals.
This last aspect allows for an easier machining of the
piston.
