RV Gravity Water Fill Port

Why This Gravity Fill Port Stands Out

• Magnetic Snap Lid: Dual magnetic closure holds the lid firmly shut at highway speed — no rattling, no wind-blown openings, opens instantly with one touch
• Built-In Tank Vent Hole: Integrated air vent prevents vacuum lock in the water tank — water flows in smoothly without gurgling, stopping, or overflow
• Rubber Dust Cap with Key Lock: Tight-sealing rubber plug blocks dust, insects, and debris from entering the fill port — keeps your water supply clean and hygienic
• ASA Material: UV-resistant, impact-resistant engineering plastic — won’t yellow, crack, or warp after years of outdoor sun exposure
• IP44 Weatherproof: Splash-resistant rated — safe for permanent outdoor installation on RV sidewalls in rain and road spray
• Standard 79×79mm Cutout: Fits most RV and caravan sidewall panels — straightforward installation with included screws
• 40mm Hose Connection: Compatible with standard 40mm gravity fill hoses and funnels

Key Design Details

• Magnetic lid: Snaps shut automatically — stable and secure, won’t move in transit
• Tank vent hole: Prevents water tank vacuum — ensures smooth, uninterrupted gravity filling
• Rubber dust cap: Blocks dust and insects from entering fill port — hygienic protection between fills
• Compact profile: 13cm wide × 14.5cm tall — low-profile flush mount blends into RV exterior

*Manual measurements may have ±1mm tolerance. Confirm cutout dimensions before installation.
