Contamination can cause significant damage to the rod, cylinder wall, seals, and other components, and is one of the primary causes of premature seal and component failure in a fluid power system.

Hallite offer a wide range of hydraulic wipers in High Performance Hallite® 361 polyurethane, Nitrile®, Hythane® 181 and other polyester based materials, along with press-fit metal caged ranges.

The wiper seal is the most undervalued seal type in the hydraulic cylinder in relation to its important function. Particular attention should be drawn to its selection, the surrounding environment and service conditions must also be taken into special consideration.
