Wipers

A Wiper is a type of seal used to exclude contaminants from entering the cylinder. Besides direct wear to the rod seal, external contamination entering a hydraulic system can have disastrous consequences.  Contaminated hydraulic fluid can quickly wear out seals, clog filters, and damage machined surfaces. However, a wiper can induce a pressure difference between the wiper and the main rod seal, which can cause either the wiper or rod seal to be ejected from its groove.

J Royal sells many different kinds of wipers, from relatively low pressure solid nitrile wipers, all the way up to heavy-duty metal clad ones. Many are also available in a wide variety of materials depending on the type of fluid or operating conditions the wiper experiences.
