I can't stand hose nozzles that have uneven spray patterns, leak at the adjustment screw, and deteriorate over time when dropped. So I went overboard in creating the finest nozzle available. It sprays a perfect pattern, from a conical shape to a straight stream to a wide-diameter light spray! Soft rubber protects the end from accidental hits on the car's surface or brutal drops on the pavement. The solid anodized aluminum body houses a stainless steel spray control shaft. Weighs a full pound! The rotating spray control bezel feels like it's on ball bearings. Let one of your neighbors borrow it? I don't think so. It's that nice. Designed for normal household pressure (about 6-14 gallons per minute flow). With the Shut-Off Valve you can keep the desired spray pattern without having to find it again and again. Simply make a quarter turn of the knob and the shut-off valve will immediately stop water flow. Made from anodized aluminum and brass. Designed specifically for use with our Finest Water Hose Nozzle but may be used with other garden hoses and nozzles. Both are made in America exclusively for Griot's Garage customers.
