When an RV's gravity-fill water hatch breaks, the replacement must fit the wall opening and allow the correct tank-fill and vent hoses to connect behind it. B&B Molders 94249 and 94250 are compact keyed gravity-fill hatches. They connect to the onboard fresh-water tank; they are not pressurized city-water connections.
Choose the compact gravity-fill hatch
| B&B part number | Colour | Wall opening | Outside dimensions | Factory key variants |
|---|---|---|---|---|
| 94249 | Polar white | 4⅜ × 3⅛ in | 6¼ × 5 in | 301-037-00067 (391 key); 301-037-00005 (751 key) |
| 94250 | Black | 4⅜ × 3⅛ in | 6¼ × 5 in | 301-037-00068 (391 key); 301-037-00006 (751 key) |
For this compact hatch the maker specifies 1-inch collar depth and 2¾-inch total depth. The fill spout accepts 1¼-inch or 1⅜-inch water-fill hose, and the tank-vent connection is ⅜ inch. Measure the original opening as well as the hoses.
Identify the gravity-fill components
1. Exterior keyed hatch
Protects the cap and fill spout; 94249 white or 94250 black.
2. Bayonet fill cap and tether
Covers the fresh-water opening; available without the spout.
3. Gravity-fill spout
Connects to the main 1¼- or 1⅜-inch tank-fill hose.
4. Tank-vent fitting
Separate ⅜-inch connection to the tank vent hose.
Schematic part identification; actual internal fittings and orientation must match the original manufacturer assembly.
Cap only or cap-and-spout assembly?
| Service part | Colour | Replaces |
|---|---|---|
| 94243 | Polar white | Bayonet water cap and strap only |
| 94244 | Black | Bayonet water cap and strap only |
| 94245 | Polar white | Gravity-fill spout plus cap and strap |
| 94246 | Black | Gravity-fill spout plus cap and strap |
| 94176 | Polar white | Original keyed hatch door, listed separately by B&B |
| 94177 | Black | Original keyed hatch door, listed separately by B&B |
If the hose connection and spout are sound, a cap-only replacement may be all that is required. If the spout is cracked, identify the correct cap-and-spout version. A replacement door is a separate component and does not include the hatch housing.

- Check the outside trim size and measure the actual cutout behind the original hatch.
- Confirm the fill hose and vent hose sizes at the rear of the original assembly.
- Match the door colour, hinge arrangement and 391/751 key configuration where relevant.
- Ensure the filler and tank vent are connected properly and follow the RV manufacturer's weather-sealing and tank-filling instructions.
