When looking to add flow control to sprinklers or nozzles that do not feature built-in flow control options, or in-between hoses, look no further than a Aquat Shut It Shut-Off adapter. This adapter can be installed at sprinklers, nozzles, accessories, or in-between hoses to provide complete On/Off functionality, as well as complete flow control. The heavy-duty plastic construction with a large, EZ-Grip lever features a stainless steel screw that won't rust or corrode. A precision engineered O-Ring seal ensures a leak free operation.
