The Loc-Line 3/4" X 1/2" Y Fitting takes a 3/4" Loc-Line run and splits it into two 1/2" outlets, combining the higher flow of the 3/4" system with the finer control of 1/2" nozzles.
Loc-Line is a modular, snap-together coolant hose system made from acetal copolymer, widely used in aquariums for directing return flow, building custom spray bars and aiming water exactly where it is needed.
