ABSTRACT:
A hose coupling for tractor-trailer braking systems which produce sealed hydraulic connections even in high pressure circuits, with minimum fluid loss on coupling and de-coupling. The coupling comprise male and female members which when brought together displace a sleeve along the spigot portion of the female member and simultaneously displace a plug along the bore of the male member to uncover sets of radial ports communicating respectively with supply and return passages to establish hydraulic flow and return paths through the coupling. The coupling also has means for locking the two members together.
