The Flopro Supergrip Waterstop Spray Gun 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. The extended clench mechanism ensures a permanent hose connection and it has a 'Snap Fit' stainless steel internal spring mechanism for increased durability. Ultra-tough and made using superior ABS plastics. The connectors allow a ‘Snap Fit’ to ensure easy connection to all major watering brands.
