This connector is perfect for reducing 16mm pipe down to 6mm pipe, when using large systems. It is inserted in-line at the point where an AQUAvalve is positioned. It provides a water tight connection unlike many other types of reduction fittings.

It works in exactly the same way as the 16-9mm or 16-6mm cross connector but this fitting has one connection for 9mm or 6mm pipe whereas the cross connector provides two connections for 9mm or 6mm pipe.
