Use the Compression Tee 900 Series to create a lateral line or add a row in your irrigation system. This T fitting forms a connection between three sections of supply tubing or dripline (0.940 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.
