Wipers

A wiper seal excludes contaminants from entering the cylinder. Along with direct wear to the rod seal, external contamination accessing a hydraulic system can have disastrous consequences. Contaminated hydraulic fluid can quickly clog filters, wear out seals  and damage machined surfaces. However, a wiper can induce a pressure difference between it and the main rod seal, causing either the wiper or rod seal to be ejected from its groove.

High Performance Seals offers many different types of wipers, from relatively low pressure solid nitrile up to heavy-duty metal clad ones. Several are also available in a variety of materials depending on what fluid type or operating conditions the wiper experiences.
