APG stocks the WAN20SH, a Polyurethane (AU/EU) Wiper Type WAN Wiper Seal supplied with a 2-7/8 inch inside diameter. A wiper seal scrapes dirt, moisture and debris from an extending rod before it can reach the primary seal.
The compound resists impact and shock loading, petroleum oils, and extrusion under high pressure. That behavior comes from the compound itself: Polyurethane (AU/EU) is widely chosen for very high tensile strength and load capacity, long wear life in dynamic reciprocating service. Exposure to prolonged humidity at elevated temperature or hot water and steam will shorten service life.
Common environments for this compound include hydraulic cylinders, off-highway equipment, and construction machinery.
This item is sold individually under part number WAN20SH. As always, verify media compatibility and operating conditions against the requirements of your specific application.
