For a quicker, more efficient drip emitter installation, use the Hydro-Flo™ Jet Assembly. The jet, 12 in. stake, and 24 in. of tubing with 1/4 in. barbed inlet come preassembled for convenience. The barbed inlet found at the end of tubing can be inserted into a punched hole in supply tubing, and the stake is inserted into the ground at your desired location. The fan spray emits water in a 180° half-circle pattern, and the 0.04 in. nozzle discharges water at up to 12 GPH with throw of up to a 9 ft. radius (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
