Step Seal (Rod Seal)

Step seals are high-performance rod seals featuring a PTFE ring with an elastomer energizer. Designed for single-acting or double-acting hydraulic rod applications, they provide excellent extrusion resistance and low friction. The step profile ensures stable installation and optimal pressure distribution. Suitable for high-pressure, high-speed hydraulic systems.
