DZ-40X50X8-E2FHydraulic rod seal, with primary and secondary sealing rings

These hydraulic rod seals consist of a nitrile rubber primary sealing ring and a LUBRITHANE thermoplastic polyurethane secondary sealing ring. The nitrile rubber primary lips provide improved long-term sealing performance and a greater capability to track larger radial deflections between the rod and the head.
