1. Description
Wiper seal GSZ2 of Forever Seals is suitable for cold and dusty environments and high frequency reciprocating motion. Mainly used in hydraulic and pneumatic devices, servo systems, chemical and food equipment. Excellent sliding performance, no stick-slip behavior, no viscosity, compensate for the distortion of the piston rod and plunger, compatibility with hydraulic media is very good, the remaining oil film adhered to the surface of the piston rod can be effectively blocked from the inside.
