## Product description

### Water tank cap for filling fresh water

This HEOS water tank cap is a practical solution for filling a fresh water tank in a controlled way. The cap is intended for use on water filler openings with a small diameter and also fits water tanks without an overflow. That makes it convenient for caravans, motorhomes, or other mobile applications where you want to top up water cleanly and accurately.

Thanks to its universal design, this cap is suitable as a replacement cap or as a handy addition to your water equipment. You can fill the tank more neatly and with less spillage than when working directly with a loose hose.

### Connection and practical use

The water tank cap is designed for fresh water and connects to many common filler openings. The size of approximately 77 mm makes it suitable for smaller tank openings within this size range.

In practice, this is especially useful when you:

- fill a caravan or motorhome fresh water tank
- have a small-diameter filler opening
- use a tank without an overflow
- want to top up water more cleanly and accurately

### Material and key features

This HEOS cap is made as a universal water tank cap for everyday use on the road or at the campsite. Its compact size makes it easy to carry as a replacement part or spare part.

Key features:

- brand: HEOS
- product type: universal water tank cap
- suitable for fresh water
- diameter: 77 mm
- usable on small filler openings
- suitable for water tanks without an overflow

### Suitable for camping and travel

This water tank cap is a great match for campers who want to keep their water system simple and practical. It is suitable for use during holidays, road trips, and weekend getaways where you regularly top up fresh water.

This gives you a compact and functional solution that helps you fill your fresh water tank more smoothly at the campsite, motorhome pitch, or on the road.
