Adapt from a sprinkler riser to 1/4 in. distribution tubing or dripline with the 1/2 in. FPT X 1/4 in. Barb Swivel Elbow. Attach the 1/2 in. FPT connection point to the riser and connect 1/4 in. distribution tubing (A220 and A250) or 1/4 in. DuraFlo™ JR dripline to the barbed swivel elbow. Swivel elbow prevents tubing from kinking or bending. Fitting is made of ABS plastic and treated with UV inhibitors to prevent fading and cracking.
