Close off the end of supply tubing or dripline (0.680 in. to 0.704 in. OD) using the Compression End Cap 700 Series. Tubing fits into the compression ring, where an internal barb compresses the tube and holds it in place. This fitting has a removable cap to flush out the line as needed. 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.
