ROD WIPER (D STYLE) 4 SLOTTED HEEL

Part number WD4000SH is a Polyurethane (AU/EU) Wiper Type WD Wiper Seal with a 4 in inside diameter. A wiper seal keeps abrasive contamination out of the cylinder, dramatically extending seal and rod life.

Polyurethane (AU/EU) is specified here for toughness that outperforms conventional rubber compounds and long wear life in dynamic reciprocating service. The material holds up against impact and shock loading, extrusion under high pressure, and petroleum oils. It should not be specified for service in ketones or prolonged humidity at elevated temperature.

Maintenance and OEM teams specify it across off-highway equipment, mining and heavy equipment, and hydraulic cylinders.

WD4000SH ships individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
