Buying Guide

Key purchase considerations for caravan water tank fittings include material, thread types, and compatibility. Brass fittings offer durability and corrosion resistance but can be heavier and more expensive than plastic options. Identify the correct thread standard (NPT, G, or garden hose thread) and verify the thread pitch and outer diameter to ensure a proper match with your tank fittings and hoses. Bulkhead fittings should provide a tight seal with gaskets or washers, and consider whether extra sealing tape or sealant is necessary for your setup. For gravity-fill systems, choose components with appropriate barbed connectors and sizes that fit your hoses, and ensure UV-resistant materials for outdoor exposure. Compatibility with holding tanks, pumps, and strainers is crucial, so review whether kit contents cover grommets, probes, and sensor needs if you plan a full install. Finally, confirm installation ease—some kits emphasize self-sealing grommets and swivel adapters that simplify routing in compact RV spaces. Collectively, these considerations help balance reliability, ease of use, and long-term durability in caravan water systems.
