Gardiner 5/16 Inch Push-Fit Metal On/Off Valve

This fitting is 5/16 inch on both sides. It can be used to connect two lengths of 5/16 inch waterpole hose together and give you a place to shut off the waterflow. For a stronger connection that won't accidentally come lose, use the red safety end clips. There is also a lighter, plastic on/off valve. See the related items below.
