Wiper Seal, 1-1/2"X1-7/8"X3/16"

Wiper Seal, 1-1/2"X1-7/8"X3/16"

The ST-150 Wiper Seal (1-1/2" x 1-7/8" x 3/16") is a precision-molded rod wiper designed to keep contaminants out of hydraulic cylinders and sealing systems. Constructed from 90A durometer urethane, this Style ST wiper ring offers the flexibility needed to snap easily into a groove while remaining tough enough to withstand demanding rod wiping applications. Its design removes dirt, moisture, and debris from the rod surface before they can enter the cylinder, helping protect internal seals and extend equipment life. Some variations are available in fluorocarbon for higher temperature applications, while versions with slotted heels allow excess hydraulic fluid to bypass the seal to prevent blowout—because hydraulic systems work best when the only thing moving in and out is the rod, not the dirt.
