Choose 16-9mm for AQUAvalve5 and 9mm Fittings
Choose 16-6mm for older, pre-August 2020 AQUAvalves with 6mm Fittings
These connectors are perfect for reducing 16mm pipe down to 9mm or 6mm pipe, when using large systems. They are inserted in-line at the point where an AQUAvalve is positioned. They provide a water tight connection unlike many other types of reduction fittings.
