The Compression Elbow 710 Series forms a 90° corner in your irrigation system. This El fitting connects two sections of supply tubing or dripline (0.704 in. to 0.710 in. OD) at an angle to prevent kinking. Tubing is inserted into the compression ring, where an internal barb compresses the tube and holds it in place, creating a watertight connection. This compression fitting is made of ABS plastic treated with UV inhibitors to prevent fading and cracking. Use fittings to set up a new drip irrigation system, expand an existing system, or make repairs.
