Characteristics and performance
The Hallite 80 double-acting swivel seal, or rotary pressure seal, is designed specifically for use in hydraulic swivel joints with an internal rotating rod, particularly in housings to Asian design. This design is a one-piece seal that can replace the two part seals typically used in this application.
With a moulded groove in the dynamic face to improve sealing against the surface while trapping lubrication and reducing the surface contact area, the Hallite 80 reduces running friction. Special pressure activation grooves are incorporated into design of the seal to enable an immediate seal of the joint.
