To make your underground sprinkler system also function as a low-flow drip irrigation system, this is the adapter you need. The 1/2 in. FPT X 1/4 in. Sprinkler Riser to Drip Tubing Conversion Adapter threads onto the sprinkler riser & outlets through the sprinkler head on top as well as through the 1/4 in. supply tubing or dripline inserted into the side compression ring. A filter washer inside the adapter ensures a watertight fit and screens out particles before they can clog the system. This adapter is made of acrylonitrile butadiene styrene (ABS) treated with UV inhibitors to prevent cracking.

• • Convert an underground sprinkler system to function as both a low-flow drip system and sprinkler system; Works with existing underground sprinkler systems
• • 1/2 in. FPT inlet connects to sprinkler riser; outlets to sprinkler as well as 1/4 in. tubing or dripline with outside diameter of 0.250 in.
• • Thread the 1/2 in. FPT inlet onto a sprinkler riser with a 1/2 in. MPT connection point, and attach sprinkler head on top; connect 1/4 in. distribution tubing or dripline into the compression fitting on the side
• • Turns existing underground sprinklers into both a sprinkler system and low-flow drip system
• • Compression fitting creates a watertight seal; internal barb that compresses the inserted tubing to hold it in place; unlike a barbed fitting, the tubing is not stretched out to connect to the fitting
• • Filter washer inside the adapter ensures a watertight fit and screens out particles before they can clog the system
