LGRIG® Stainless Steel Marine Deck Fill with Key is designed to provide a secure and convenient connection between a boat’s deck and onboard fuel, water, diesel, gas or waste tanks. This hose deck fill combines a durable stainless steel body, threaded cap, retaining chain and deck fill key, providing reliable access for filling or servicing marine tanks while helping prevent the cap from being lost.
Constructed from marine-grade 316 stainless steel, this stainless steel deck filler offers excellent corrosion resistance and durability in demanding freshwater and saltwater environments. The polished surface provides a bright, mirror-like appearance that complements modern boats, yachts and other marine hardware. The replaceable sealing ring helps create a secure connection and helps keep water and contaminants away from the tank system.
The deck fill with key is available in 1-1/2-inch and 2-inch sizes to accommodate different hose and tank configurations. Clear identification such as FUEL, DIESEL, WATER, WASTE or GAS helps users select the correct filling point and reduces the risk of cross-filling.
Ideal for boats, yachts, marine vessels, caravans, RVs and other tank systems, this stainless steel hose deck fill is suitable for new installations, replacement projects and marine hardware upgrades. Its robust construction, practical key-operated cap and corrosion-resistant finish make it a reliable choice for professional marine deck filling applications.
