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

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

The ST-112 Wiper Seal is a precision hydraulic rod wiper designed to keep dirt, dust, and contaminants from entering hydraulic cylinders while wiping excess fluid from the rod during operation. Manufactured from durable 90A durometer urethane, this wiper ring is flexible enough to snap easily into a groove while remaining tough enough to handle demanding rod-wiping applications. Designed for a 1-1/8" rod, it helps extend seal life and maintain proper hydraulic system performance by keeping contaminants out—because the best hydraulic problems are the ones that never make it inside the cylinder.
