1. Description
SPGW of Forever Seals is suitable for long stroke, a wide range of fluids and high temperature occasions. The application of heavy duty double acting piston sealing under high pressure conditions is excellent. Applicable to larger piston clearance , it has good leakage control, extrusion resistance and wear resistance in heavy duty and construction machinery cylinder piston sealing system. Good static sealing property, simple groove structure, larger extrusion clearances can be allowed, be able to work in dusty condition.
