APG stocks the WD7000SH, a Polyurethane (AU/EU) Wiper Type WD Wiper Seal supplied with a 7 inch inside diameter. A wiper seal scrapes dirt, moisture and debris from an extending rod before it can reach the primary seal.
The material holds up against impact and shock loading, extrusion under high pressure, and ozone. Polyurethane (AU/EU) is valued for very high tensile strength and load capacity, outstanding extrusion resistance at elevated pressure. It should not be specified for service in ketones or hot water and steam.
Common environments for this compound include hydraulic cylinders, off-highway equipment, and construction machinery.
Stocked as WD7000SH and sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
