Deliver low volume overhead watering to gardens, flower beds, ground cover, and hillsides with the Micro Spray Jet. Stream spray emits water in a full-circle pattern up to 12.9 GPH, with a radius of up to 9.0 ft. (at 15-50 PSI). Jet has a 10-32 threaded inlet which screws onto a rigid riser with stake (not included); use 1/4 in. supply tubing to connect to the inlet barb found on the stake. The Micro Spray Jet operates at low pressures. Keep the jet from taking off by using a pressure regulator at the water source to reduce pressure. Micro Jets are made of polyethylene treated with UV inhibitors.
