Dura swing joints are used to go between the underground pipe work (usually HPPE or MDPE) into the bottom of a sprinkler. They allow for fine adjustment of sprinkler height but also for the sprinkler to 'flex' if direct pressure is applied directly on the top. Male BSP inlet x male ACME threaded outlet. Swing joints are 12" or 18" long and the extra inlet elbow option (4 elbows) allows top connection to the lateral pipe saddle.

Toro branded swing joints are manufactured by Dura.
