The Hydro-Flo™ Jet Assembly means less work for you. Made for easier drip irrigation installation, the jet, 12 in. stake, and 24 in. of tubing with 1/4 in. barbed inlet come preassembled for your convenience. Simply connect the barbed inlet found at the end of tubing into a punched hole in supply tubing, and stake the system into the ground. The fan spray emits water in a 90° quarter-circle pattern, and the 0.06 in. nozzle discharges water at up to 28 GPH with a radius of up to 11 ft. (at 30 PSI). The Hydro-Flo™ Jet Assembly is made of polyethylene, vinyl, and ABS plastic, treated with UV inhibitors to prevent fading and cracking
