In the private sector usually water connectors (Gardena couplings) made of plastic are used. The plastic brittles and does not satisfy our sense of quality.
We provide a coupling with 1 inch (30.3 mm) internal thread made of resilient brass. You can screw it on both taps, ball valves and IBC-connectors with corresponding 1 inch thread.
The Gardena-fitting is flat sealing, we supply it with an internal gasket of NBR rubber.
