Gen3 Marine Stainless Steel Water Deck Fill with Key, 1-1/2 Inch Hose, 316 Stainless Steel

The Gen3 Marine Water Deck Fill (part number 5-9002) is a 316 stainless steel deck fitting used to fill a boat's freshwater tank from the deck without opening a hatch or accessing the tank directly. It is built for a 1-1/2 inch hose connection and mounts flush to the deck, giving marine and RV builds a corrosion-resistant, low-profile fill point that holds up to sun, salt spray, and regular deck traffic.

The cap uses a slotted, straight-thread design that requires a key to open, adding a layer of security against unauthorized access to the fresh water system. The key is attached to the deck fill body by a chain, so the cap cannot be set down and lost or dropped overboard while the tank is being filled. The entire fitting -- body, cap, and chain -- is made from 316 stainless steel, a marine-grade alloy chosen for its resistance to rust and pitting in saltwater environments.

This deck fill measures 3-1/4 inches in length with a 3 inch diameter opening and connects to 1-1/2 inch hose. It ships with the key included; mounting hardware is sold separately.
