Designed for convenient and reliable water tank filling on boats and other marine applications, this Nylon Deck Fill with Keyless Cap provides a practical connection between a 1-1/2" hose and a water tank. Made from durable injection-molded nylon, the marine water deck fill offers a lightweight construction and excellent suitability for demanding outdoor and marine environments.
The integrated keyless cap allows the cap to be opened and removed without a separate deck fill key, making routine tank filling and maintenance simple and convenient. The hinged opening mechanism can be operated directly from the cap and remains attached to the deck fill by a retaining chain, helping prevent accidental loss while the tank is being filled.
The blue cap is clearly marked “WATER” for quick identification and helps distinguish the water tank connection from fuel, diesel, oil or waste fittings. With a 1-1/2" hose connection, this nylon deck fill is suitable for water tank installations on boats, yachts, fishing boats, recreational watercraft and other marine equipment.
Its compact design, smooth molded surface, lightweight nylon construction and convenient keyless cap make it a practical choice for both replacement and new installation projects. This water deck fill combines easy operation, clear identification and dependable marine performance.
