The HS-U90 is a durable, static head seal that replaces the O-ring and backup ring at the top of the cylinder. Its symmetrical one-piece design prevents common failures like backup blowout and pinched backups, especially in cylinders with high eccentricities or large extrusion gaps. The unitary design reduces installation damage and simplifies assembly. Sizing corresponds to AS568 inch sizes.
