1/2" Rod Wiper Seal Snap-In D-Style 95A Polyurethane

This 1/2 inch rod wiper seal is designed to keep hydraulic systems running clean, efficient, and protected. Its job is simple but critical: wipe dirt, dust, moisture, and debris from the rod before contamination can enter the cylinder. The result for the customer is longer seal life, reduced downtime, and lower repair costs.

Manufactured from 95 durometer polyurethane (AU), this snap-in, single-acting D-style wiper delivers excellent abrasion resistance and durability in demanding hydraulic environments. The beaded heel ensures a secure press fit, making installation fast and reliable. This is a proven choice for maintenance, repair, and OEM hydraulic equipment where rod protection matters.
