Create a lateral line or add a row in your irrigation system using the Compression Tee 700 Series. This T fitting connects three sections of supply tubing or dripline (0.680 in. to 0.704 in. OD) or adds an intersection in your line. 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.
