The HEOS® Water Connector Universal is a high-quality solution for clean and efficient filling of your RV’s fresh water tank. Designed with versatility in mind, this connector is a suitable replacement for all current filler plugs with a bayonet lock (Ø 77 mm) and includes features that make it compatible with a wide range of RV models and tank configurations.

Thanks to the enclosed flat rubber seal, the connector works seamlessly with water tanks that feature an overflow system, ensuring a reliable seal every time. Need to fit a smaller filler plug? Simply swap the seal with the included additional ring, and the HEOS® Water Connector adapts to smaller filler plugs (cap Ø approx. 67 mm) — perfect for models like Dethleffs, LMC, and TEC from 2010 onward, or any water system using the same standard.

The flexible cap seal is designed to prevent overpressure in your tank. If pressure builds up, the connector automatically opens slightly to release air or water through the filler plug, maintaining safe internal tank pressure during the fill process.

⚠️ Note: The HEOS® Water Connector does not automatically stop the water flow when your tank is full. Always monitor tank levels during filling.
