The Loc-Line 1/2" Male NPT Valve combines a male NPT threaded connection with a built-in shut-off valve, so you can thread a 1/2" Loc-Line directly into a fitting and control or stop flow at the source.
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.
