Join two sections of supply tubing or dripline (0.940 in. OD) using the Compression Coupling 900 Series. This coupler forms a watertight connection between tubing sections. Tubing is inserted into the compression ring, where an internal barb compresses the tube and holds it in place. 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.
