3/8” brass fittings. The cube is a 3-way junction, then two screw in hose fittings. The one with the tangs is just a hose fitting filed away on both sides. (Brass is hard so I took some away with a Dremel and tiny 1” cut off wheel that came with the Dremel kit.) then finished it off with a flat file till the tangs fit the lock nut slots.
