The Whale AquaSource to Truma Crystal II Adaptor EM9407 allows compatible Whale AquaSource, AquaSmart and Watermaster water connections to be used with Truma Crystal II and Compact Mk2 water inlet sockets, providing a secure and convenient caravan mains water connection.
Designed to bridge the connection between Whale and Truma water systems, this genuine Whale accessory is particularly useful for caravan and motorhome owners who want to use their existing Whale water equipment with a vehicle fitted with a Truma Crystal II external water inlet.
The adaptor provides a straightforward solution when the connector on your Whale water supply equipment does not directly fit your caravan’s Truma inlet housing. Rather than replacing your existing water connection equipment, the EM9407 allows compatible components to be connected together, helping reduce unnecessary expense.
One of its main advantages is its compatibility with multiple Whale water connection systems, including Whale AquaSource, AquaSmart and Watermaster plugs. This makes it a useful accessory for touring enthusiasts who already own Whale water equipment but have a caravan fitted with a Truma Crystal II or Truma Compact Mk2 socket.
The adaptor is particularly beneficial when using a Whale AquaSource mains water hook-up kit, allowing the appropriate Whale connector to be attached to a compatible Truma Crystal II inlet. This provides a practical solution for connecting to a serviced campsite pitch with a mains water supply.
Featuring a secure twist-lock connection, the adaptor is designed to fit into the compatible Truma socket housing and hold the connection in place during normal use. Its straightforward fitting process makes it convenient to connect and disconnect when setting up or packing away your caravan.
The compact and lightweight construction makes the EM9407 easy to store alongside your existing water hoses, connectors and campsite accessories. It takes up very little storage space, making it a practical spare to keep in your caravan or motorhome.
Manufactured by Whale, the adaptor is designed specifically for compatible water inlet connections, providing a purpose-made alternative to improvised fittings.
Whether you are changing caravans, upgrading your water connection equipment or adapting an existing Whale mains water kit, this genuine replacement accessory provides a convenient solution.
Connect your Whale water equipment to compatible Truma Crystal II sockets with the genuine Whale EM9407 Adaptor, offering easy installation, reliable compatibility and convenient mains water hook-up.
