Hunter 1/2" x 30cm swing joints are used to connect pop-up sprinklers to irrigation pipework while allowing the sprinkler height and position to be adjusted during installation. They are suitable for landscape irrigation systems where a longer flexible preassembled swing joint is preferred over a rigid riser.
This Hunter SJ-512 swing joint is a 1/2" x 30cm preassembled assembly with four swing elbows. The swing joint helps reduce stress on sprinkler connections and makes sprinkler positioning easier during installation and servicing.
