Wiper Seal, 2"X2-1/2"X1/4"

Wiper Seal, 2"X2-1/2"X1/4"

The ST-187 Wiper Seal is a precision-molded hydraulic rod wiper designed to protect cylinder systems by keeping dirt, dust, and contaminants out while wiping excess fluid from the rod during operation. Manufactured from durable 90A durometer urethane, this ST-style wiper ring combines flexibility for easy installation with the toughness needed for demanding rod-wiping applications. Designed for 1.875" rods, the seal measures 1.875" ID × 2.250" OD × 0.188" height, helping extend hydraulic cylinder life—because the best hydraulic repairs are the ones you never have to make.
