The Aqua Stop connector has an internal valve that stops the water flow when an accessory (eg a spraygun ) is disconnected. This saves you having to go back to the tap to turn the water off when you are switching between accessories. 
Suitable for use with all 19 mm /3/4in and 15 mm /5/8in hose.
All internal parts are made from ultra tough engineering plastics for a long leak free life.
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 because of the twin soft touch pads.
The hose is firmly connected thanks to barbs that connect with the inside and outside of the hose.
Hose kinking , Hose swelling, and hose leaking at the connection point with the fitting is virtually eliminated due to the ingenius flexible hose-tail on the nut.
