Sea-Dog Stainless Steel Cast Hose Deck Fill Fits 1-1/2" Hose - Gas

The Sea-Dog Stainless Steel Cast Hose Deck Fill for 1-1/2" hose (gas application) is a marine-grade fuel filler assembly engineered for vessels requiring secure, corrosion-resistant fuel access. Constructed from investment-cast 316 stainless steel, this deck fill is designed for saltwater environments and delivers the durability necessary for offshore and coastal vessel operations where traditional mild steel fillers fail rapidly.

This hose deck fill features a slotted cap design requiring a key for opening and closing, adding a security layer that prevents unauthorized fuel access or accidental spillage during operation. The 1-1/2" hose connection accommodates standard marine fuel line sizing, while the 1-7/8" cap diameter with 11-1/2 NPSM straight thread pitch ensures compatibility with Sea-Dog installation systems. The assembly includes an integral attachment chain, securing the cap while refueling and preventing loss overboard. Investment casting in 316 stainless steel ensures superior corrosion resistance compared to lower-grade stainless or aluminum alternatives, critical for salt-air exposure.

This product serves boat owners, marine mechanics, and vessel maintenance professionals who need reliable fuel system components for gasoline-powered outboards, inboards, and auxiliary systems. Deck fills rated for 1-1/2" hose are standard on mid-sized pleasure craft, sport fishing boats, and commercial vessels where fuel capacity and feed-line sizing demand this specification. The keyed-cap security feature is particularly valuable on moored or parked vessels in active marinas where fuel theft or contamination risk exists.

Sea-Dog is established in marine hardware manufacturing, known for stainless steel fittings that withstand extended saltwater service. Hose deck fills are foundational fuel system components; selecting 316 stainless construction and keyed security represents a long-term investment in fuel system integrity and vessel safety.
