Truma Ultraflow caravan water inlet (Truma Ultraflow socket)

Used on: caravans and motorhomes fitted with a Truma Ultraflow external water socket and submersible pump.

The Truma Ultraflow socket accepts a Whale Watermaster connector directly, which is why one hook-up kit covers most modern vans. The older Truma Crystal II socket is a different fit and needs a dedicated adapter rather than forcing the Watermaster in.

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.
