We provide swivel joints that range from 1" to 4" and can handle up to 6,000 psi for standard service. Also available are long sweep swivel joints, which are designed to withstand working pressures of 7,500 to 20,000 psi. Long sweep swivel joints for sour service are rated up to 15,000 psi. All swivel joints have three key features, one they are made from heat-treated material to withstand high pressures. Second, they have a dual-purpose packing composed of an anti-extrusion ring to reduce friction, and an active seal to prevent the fluid from leaking. All swivel joints have smoothbore finishes to ensure smooth flow.
