The HS-U90 Head Seal is a durable static head seal molded from 90A urethane and designed to replace the O-ring and back-up ring at the top of a hydraulic cylinder. Its symmetrical one-piece design helps prevent common installation and operating failures such as back-up blowout and pinched back-up rings, particularly in cylinders with high eccentricity or large extrusion gaps. The unitary construction also reduces installation damage and simplifies assembly.
