Filling your RV fresh water tank without a lockable cap means risking accidental opening on the road, dust and debris contaminating your drinking water, and slow, gurgling fills caused by air pressure buildup. The RV Lockable Gravity Water Fill Cap solves all three: a key-lock lid keeps the port sealed and secure during transit, while the integrated 10 mm vent tube lets air escape as water flows in — giving you a fast, splash-free, pressure-free fill every time.

🔺 Product Details

Key Features

Key Lock Security – Prevents accidental opening during transport, keeps dust and unauthorized access out. Two keys included.
Water Fill & Vent Integrated – Large-diameter main inlet for fast filling plus a dedicated 10 mm vent tube that vents tank air simultaneously — no backflow, no splashing, no air lock.
Built-In Spring Mechanism – Internal spring keeps the lid sealed under pressure, improving watertightness and preventing leaks between fills.
O-Ring & Perimeter Gasket Seal – Dual sealing: O-ring on the cap prevents water ingress, perimeter gasket on the flange stops rainwater from seeping in after the lid is opened.
Clear Fresh Water Marking – Embossed fresh water symbol on the cap for instant identification — no more confusing your water inlet with other exterior ports.
Easy Flush-Mount Installation – Recessed design sits flush with the RV exterior wall. Includes mounting screws and gasket. Available in White and Black.
