Put a stop to the flow of water at the end of your tubing or dripline with the 0.710 in. Compression End Cap. To install， insert the tubing into the compression ring， and an internal barb compresses the tube for a watertight connection. Comes with a removable cap so you can easily flush out the line as needed， or expand your system. If you are having trouble inserting tough tubing， try softening the ends by soaking them in hot water， or leaving the tube out in the sun. The compression end cap is made of acrylonitrile butadiene styrene (ABS) treated with UV inhibitors to prevent cracking.Find the IRRIGATN HOSE PLUG 3/4 at Ace.
