Used on: The external thread on most modern kitchen and bathroom tap spouts.
Tap-spout aerator threads are fine (27 TPI or 1 mm pitch) and are not a hose thread. A tap-to-hose connector adapts the aerator thread to GHT or BSP.
Quick-connect click fittings from Hozelock, Gardena and Karcher are proprietary and do not interchange. They all sit on top of a standard thread underneath, so the reliable way to move between brands is to adapt at the threaded tap or hose-end fitting, then use each brand's own connector above it.
