CH type
Piston seals
Features
CH type is a dust ring composed of an irregular PTFE ring and an O-ring. It is suitable for harsh external environment and high frequency reciprocating motion. Excellent sliding performance, no sticking and creeping phenomenon, can compensate for the deformation of the piston rod, very good compatibility with hydraulic medium, can effectively block the remaining oil film on the surface of the piston rod from the inside.
