The Flopro Professional Elite Water Stop Hose Connector has an internal valve that stops the water flow when an accessory like a spray gun is disconnected. This saves having to return to the tap to turn the water off when switching between accessories. It also eliminates water wastage. Pull back larger section of connector to insert or release. Made from metal for improved durability. The connectors allow a ‘Snap Fit’ to ensure easy connection to all major watering brands. Comes with a 10 year guarantee.
