Use the Compression End Cap 900 Series to seal off the end of supply tubing or dripline (0.940 in. OD). Tubing is inserted into the compression ring, where an internal barb compresses the tube and holds it in place. The removable cap makes it easy 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.
