PU5 Wiper

8056

Rod wiper with additional static sealing lip and support components; sealing edge of wiping lip lightly chamfered. Single-acting wiper. The additional static sealing lip prevents ingress of dirt and water spray. The wiper lip with lightly rounded sealing edge wipes dirt away safely and leaves a residual oil film on the retracting rod. The support on the wiper heel prevents twisting in the groove as well as pressure build-up between wiper and seal. Made in Polyurethane 95 Shore A.
