Connect Whale Watermaster caravan water inlet to Truma Ultraflow caravan water inlet

How to join Whale Watermaster socket and Truma Ultraflow socket, and what stops it leaking.

Direct fit
End A
Whale Watermaster caravan water inlet (Whale Watermaster socket)
Seals on a washer at the face
joins direct
End B
Truma Ultraflow caravan water inlet (Truma Ultraflow socket)
Seals on a washer at the face
Adapter needednone

These connect directly. Whale Watermaster caravan water inlet mates with Truma Ultraflow caravan water inlet without an adapter.

A Whale Watermaster connector fits both Whale Watermaster and Truma Ultraflow inlet sockets, so the two brands are directly cross-compatible and one hook-up kit serves most modern vans. Older Truma Crystal II sockets are the exception and need a dedicated adapter.

Check which socket your van actually has before buying. A Watermaster connector will not clip into a Crystal II socket; that older Truma fit needs its own adapter, not force.
