The 500 type double-acting swivel seal, or rotary pressure seal, is designed specifically for use in hydraulic swivel joints for either rod or bore sealing applications. The patented design minimises friction between the seal and the rod or bore mating surface. Depending on size, the seal is either a one-piece design or has two acetal anti-extrusion rings which allows for larger extrusion gaps. Both of these configurations can replace the two part seals typically used in this application. Special pressure activation grooves are incorporated into the design of the seal to enable an immediate seal of the joint. The seal is manufactured in Hythane 181, Hallite's high-performance polyurethane, for easy installation, excellent low temperature performance, and long service life.
