Description: 1/2" Ball-Socket MPT Valve (Loc-Line)
Loc-Line Aquarium Supplies
Loc-Line is the originator of the modular hose system. They offer a selection of hose sizes, various nozzles, connectors and accessories that can be assembled to optimize liquid, air, vacuum and gooseneck applications. After years of being frustrated by metal coolant hoses that never would stay where they were aimed and plastic hoses with metal positioning rods that broke, Arnold Lockwood conceived the idea for a modular hose that became Loc-Line. In 1981 Lockwood Products was started to develop that idea and the first Loc-Line was shipped in August of 1983. It quickly became the standard for low pressure coolant delivery and equally as quickly spread around the world.

I bought 6 sets of the Loc-line jets with the MPT ball valve for a distributed return around the tank. These works well, allowing great flexibility in aiming and controlling the water flow. The only problem I had was with the valves themselves. Some of them are very tight to turn. My fingers hurt after each time I turn them. Salt deposits do form onto these pipes above the waterline. Be careful when you knock the salt off that they don't land on your precious coral. One tip: you don't really need their tool to put the pieces together. They can easily be pushed together. Don't know about pulling them apart. Haven't tried it yet.
