The Master-FLO hose valve is jam packed with features every DIY-er will appreciate! FLOW CONTROL: The Master-FLO valve features begin with a full 5/8 in. I.D. (same as a standard water hose), enabling maximum force by minimizing water friction. Then, extended control lever enables precise, continuous control of water volume flow (turning clockwise) to meet exact need. SHUT OFF: when turned fully, the valve shuts the water off, up to 125 PSI. This is an important feature when using a nozzle with no shut-off such as a fixed sweeper nozzle. The SWIVEL BASE works effortlessly to avoid hose kinks. The COMMERCIAL LENGTH MALE (THREADED) END ensures that the Master-FLO valve can be used with any residential or commercial nozzle which may have a deeper hose coupler. The Master-FLO flow control and shut-off valve will make all watering jobs easier and more efficient.
