The GF 8000-24 tap adapter screws onto a 3/4" (19 mm) threaded tap and accepts quick-fit garden hose connectors. It also comes with an adapter for kitchen and bathroom mixers with M24x1 external and M22x1 internal threads, so the same hose set works indoors too.

Brass 3/4" threaded connection

The brass section takes repeated fitting and removal without wearing the thread. A standard 19 mm quick-fit hose connector clicks straight onto it.
