Application and properties
Applicable to construction machinery, construction machinery and automotive equipment and other industrial fields. Consisting of a sealing ring, a O-Ring and two retaining rings, the sealing surface profile is specially designed to accommodate high pressure and low speed, the design of the back of the seal ring increases the contact surface and prevents rotation with the rod or shaft. Low friction, non viscous phenomenon, simple groove, good abrasion resistance and dimensional stability.
Standard materials
Sealing ring: filled PTFE
O-Ring: NBR / FKM
Back-up ring: POM / PA
