Features

The swivel joints are widely used in hydraulic piping for such as construction equipment, machine tools, general industrial machines, etc.
Specially used in hydraulic pressure piping and they show excellent performance against low-speed rotation and/or reciprocating rotational motion.
Mainly above types are used for connections between fixed piping and high-pressure hoses preventing hose torsion.
