Swing joints are the best way to protect and set sprinkler heads. Blu-Lock swing joints are stronger, more adjustable, and reusable. The double elbow design adapts to the needs of the irrigation system by allowing for various angles, heights, and positions. The elbows rotate and allow the pipe to flex when weight is on them. The Blu-Lock swing joint incorporates push-fit technology. Our push-fit parts have tabs on the ends of each fitting that release and allow one piece to attach at a time, eliminating problems caused by nearby sidewalks, pipes, or other obstructions. You can release and cut the pipe to the length you need. Pre-assembled swing joints from other manufacturers come in one length, and the pipe cannot be disassembled. Blu-Lock is faster and more versatile than barbed fittings. This swing joint has 3/4 in. Male Pipe Threads on one end and 1/2 in. MPT on the other, which fits Voyager and other rotors with 3/4 in. threaded inlets.
