Our shut-off coupling operates as a shut-off valve for hose sprinklers. Use at the hose faucet connection or even at the end of a sprinkler, to adjust flow control. Our leak-free ball valve allows you to adjust the flow, whether you want it off, just a trickle or full flow. This shut-off has a swivel hose connection for easier attachment to the hose faucet. The durable brass construction means you'll be using our product for many years to come.
