The CR Wiper Seal 2.750x3.254x0.281 NBR is specifically engineered to provide effective exclusion of external contaminants from hydraulic and pneumatic systems.

Unlike conventional oil seals that retain lubricants, a Wiper Seal is designed to clean and protect the exposed rod surface during cylinder retraction. The wiping edge removes dust, dirt, sand, water, mud, metal particles, and other contaminants before they can enter the cylinder and damage internal sealing components.

The wiper seal plays a critical role in extending the life of rod seals, piston seals, bearings, guide rings, and hydraulic cylinder assemblies. Effective contamination exclusion significantly reduces equipment wear, maintenance requirements, and unexpected downtime.

Manufactured from premium NBR (Nitrile Butadiene Rubber), the seal offers excellent resistance to hydraulic oils, lubricants, grease, water, and general industrial environments. NBR provides excellent flexibility, abrasion resistance, and durability under continuous operating conditions.

With dimensions of 2.750 x 3.254 x 0.281 inch, this wiper seal is commonly used in hydraulic cylinders, construction machinery, agricultural equipment, mining equipment, lifting systems, industrial presses, and fluid power equipment.
