The swivel joints of the SJ series are designed to be mounted between a hose assembly and a rigid component of a machine in
order to allow and compensate occasional rotations: the movement of the stem on his own axis prevents hose damages.
They are used in every productive sector where there are means, equipments or plant with moving flexible hoses.
These swivel joints are also available in stainless steel AISI 316: they are black-dull owing to a special nitrocarburizing.
This basic treatment is done to avoid the danger of seizure, very high, between stem and body during rotation and also to increase
the swivel joint’s life. At last we must to remember that stainless steel joints have lower work pressures compared to the standard type.
