This plastic inline shut off valve allows you to stop flow on a liquid line without having to disconnect your keg coupler. It's perfect for bag-in-box applications, situations where there is no check ball to hold liquid in the line or instances where you just want to shut off the flow to a faucet without a faucet lock. The 3/8" barbs are great for use with 5/16" ID beer line. Also helps with flow control.
