Wiper Seal, 1.1/4"X1-5/8"X3/16"

Wiper Seal, 1.1/4"X1-5/8"X3/16"

The ST-125 Wiper Seal is a precision-molded hydraulic rod wiper designed to remove dirt, moisture, and contaminants from cylinder rods before they enter the hydraulic system. Built in the ST wiper ring style, it fits a 1-1/4" rod and is molded from 90A durometer urethane, offering the flexibility to snap easily into its groove while remaining tough enough for demanding wiping applications. By keeping debris off the rod during operation, this seal helps protect internal seals and extend cylinder life—because hydraulic systems run a lot better when the dirt stays outside where it belongs.
