Add a 90 turn in your drip system with the Smart Loc Universal Elbow, the unique fitting that accommodates multiple tubing sizes. Connect sections of 1/2 in., 5/8 in., and 0.710 in. tubing or dripline together, or transition from one tubing size to another. Installation is easy-just insert the barbed end of the fitting into the tube and twist the nut over the tubing end for a secure fit. Reusable fitting is made of acrylonitrile butadiene styrene (ABS).
