Wiper Seals

PRH SEALS offers a wide range of hydraulic Wiper seals for both single-acting and double-acting systems. In TECNOLAN & TECNOLEO.

Wipers are installed in the sealing configurations of hydraulic cylinders to prevent contaminants such as dirt, dust and moisture from entering the cylinder as they retract back into the system.
