Products & Services
Swivel Joints
Swivel joints are used in fluid and pneumatic systems that require torsional rotation between flow lines.
Ball Joints
Ball joints are flexible joints consisting of a ball with a protruding stud that has been captured inside an outer housing. They allow simultaneous limited motion in all directions, including rotation as well as angular.
Universal Joints
Universal joints are flexible mechanical connections used to transmit rotary motion from one shaft to another shaft that is not in line with the first, or when alignment varies during service.
Constant Velocity Joints (CV Joints)
Constant velocity (CV) joints are mechanical power transmission components that provide rotational power at various angles. They provide the same output velocity in relation to the input velocity, independent of the angle they are operated at.
Vacuum Flanges and Fittings
Vacuum flanges and fittings connect runs of pipe and tubing in vacuum or process gas system to other tubing sections, pipe, hose, valves, pumps, chambers or other vacuum components.
