RV Gravity Water Inlet | PP Fresh Water Tank Fill Port for RV Trailer Campervan

😣 Pain Points We Solve

• ❌ Pressurized fill systems are complicated – This gravity inlet lets water flow directly into the tank without pressurization — just insert the hose and fill
• ❌ Air locks slow down filling – The built-in vent hole design automatically releases trapped air, allowing water to flow in smoothly and quickly without gurgling or backflow
• ❌ Old inlets crack, yellow, and leak – Made from impact-resistant PP plastic that resists yellowing, deformation, and breakage even after years of outdoor use
• ❌ Dirt and debris enter the tank – The tethered screw cap stays attached so it’s never lost, and seals the port tightly to keep contaminants out between fills
• ❌ Hose doesn’t fit or keeps slipping – The 3.45cm (1.36") ribbed barb connector grips standard hoses securely without clamps or adapters
