The Orbit Proflo Metal Gooseneck Coupling operates as a shut-off valve for hose faucets. Use this coupling at the 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 metal gooseneck coupling with a swivel hose connection ensures easy installation while durable brass construction provides years of use.
