Wiper Seal, 1-3/8X1-3/4X3/16

Wiper Seal, 1-3/8X1-3/4X3/16

The ST-137 Wiper Seal is a precision-molded hydraulic rod wiper designed to keep dirt, debris, and contaminants out of hydraulic cylinders while maintaining smooth rod operation. Built in the ST wiper ring style, it fits a 1-3/8" rod and is molded from 90A durometer urethane for durability and flexibility. The design allows the seal to snap easily into its groove while remaining tough enough for demanding rod wiping applications. By clearing contaminants from the rod before they enter the cylinder, this wiper seal helps extend seal life and maintain reliable hydraulic performance—because clean rods make happy cylinders.
