Trusted water safety: Integrated locking mechanism prevents accidental openings and blocks external debris, ensuring safe, uncontaminated water storage for RV use. Tilted inlet design for nosplash filling: Tilted flowguiding structure enables smooth filling with minimal splashing, providing convenient operation in every use. Resilient build quality: Constructed with a robust combination of polypropylene (PP), zinc alloy, and iron components to resist temperature variations and sustain reliable performance in diverse conditions. Convenient doublekey feature: Includes two independent keys to minimize the risk of lockout and enhance daily usability with secure access options. Key attributes Function: A locking RV freshwater inlet that protects water from accidental opening and external contamination. Compatibility: Designed to fit standard RV freshwater inlet fittings. Size: Standard sizing appropriate for common RV inlets. Material: PP body; zinc alloy lock housing; iron components. Performance: Temperature variation resistance and durable operation across a range of conditions. Use scenarios At a campground or stopover, use the tilted inlet to fill the RV freshwater system smoothly and splash, while the locking mechanism guards against accidental openings and debris. During travel or storage, rely on the lock to prevent opening due to movement, maintaining water integrity and preventing leaks. In shared or multiuser settings, the two independent keys simplify access management and reduce downtime if a key is misplaced.
