Quick couplings
Rotary Line Cupla
The Nitto Kohki Rotary Line Cupla is a quick coupling with an integrated swivel joint, made of brass and steel with NBR seals. Two variants are offered: RT-type and RE-type. The swivel allows free rotation of the connected line around the coupling axis, preventing torsional stress and hose kinking in applications with rotating or pivoting tool carriers.
