Product Overview

Polyurethane O-Rings with a 2.4 mm cross section provide reliable sealing performance where high wear resistance, durability and mechanical strength are required. Manufactured from high-quality polyurethane (PU), these sealing rings are suitable for both static and dynamic sealing applications in demanding industrial environments.

Compared with conventional rubber O-rings, polyurethane offers superior abrasion resistance, excellent tear strength and longer service life, especially in applications involving movement, pressure and repeated operation.
