Hallite® rod seals

Hallite® rod seals

The rod seal is the most critical seal on any type of hydraulic equipment to prevent fluid leakage from the cylinder to the outside. Leakage through the rod seal can reduce equipment performance and, in extreme cases, can also cause environmental problems. Hallite® offers a wide range of hydraulic rod seals for both single-acting and double-acting systems. These include a unique profiled NBR energised polyurethane (PU) seal and a specially designed three-element seal for the mining industry consisting of an O-ring energiser, PU casing and a polyacetal anti-extrusion ring. For best sealing performance, special attention should be paid to combining the rod seal and energiser. If a less aggressive rod seal is combined with an aggressive wiper, the wiper may scrape the microscopically thin oil film remaining on the rod into microscopic surface imperfections during recoil, resulting in system leakage.
