The AquaStop Plus Connector has an internal valve that stops the water flow when an accessory eg a spray gun is disconnected This saves having to go back to the tap to turn the water off when switching between accessories It also helps save water in the garden by stopping the water flow thus preventing water from being wasted All internal parts are made from ultra-tough engineering plastics for a long leak free life and the connection to the tap is guaranteed secure up to 10 bar thanks to a triple locking system The sleeve is easy to use even when wet due to the twin soft touchpads and the hose remains securely connected via the barbs that connect with the inside and outside of the hose Hose kinking swelling and leaking at the connection point with the fitting are virtually eliminated due to the ingenious flexible hose-tail on the nut This fitting is best used at the gun end of the hosepipe Suitable for use with all 19mm 34in and 15mm 58in hose
