Add a row or lateral line to your drip irrigation system with the 0.710 in. Compression Tee. Use the T fitting to join three sections of 0.710 in. supply tubing or dripline together or add an intersection to your line. Tubing is inserted inside the compression ring， where an internal barb compresses it to create a watertight connection. If it is difficult to connect tubing， try softening the material by soaking the tube ends in hot water or leaving out in the sun. This compression fitting is made of acrylonitrile butadiene styrene (ABS) treated with UV inhibitors to prevent cracking.Find the TEE COMPRESSION .710 at Ace.
