Engineered for tight plumbing configurations on the pad, this flush union joins a 1.5-inch male threaded equipment port to 1.5-inch PVC pipe using a glue-in slip socket. Its shortened body sits close to the housing to maximize space, while the threaded union nut and integrated rubber O-ring maintain a pressure-tight seal. Incorporating this piece into your setup lets you unhook equipment for off-season storage or repair without disturbing the surrounding pipe work.
