NRC&XRC 1-1/2" (38mm) Boat Fuel Deck Fill — 316 Stainless Steel, Keyless Cap, Polished

NRC&XRC 1-1/2" (38mm) Boat Fuel Deck Fill is a polished 316 stainless steel, keyless marine fuel filler with a screw-off top, pull-out lug and safety chain designed for secure fuel access on boats, yachts and caravans.

This heavy-duty deck fill by NRC&XRC is made from AISI 316 stainless steel and finished with a precision polish using a lost-wax process to deliver corrosion resistance and a clean, marine-grade appearance. The unit fits a 1-1/2" (38mm) cutout and stands 84mm tall, offering a compact profile that keeps the fueling point accessible without taking up excessive deck space. Its keyless cap design and integrated safety chain simplify use while reducing the number of loose parts to manage during refueling.

How does this deck fill handle saltwater and outdoor exposure?

The NRC&XRC deck fill is constructed from AISI 316 stainless steel, an alloy chosen for its superior resistance to chloride-induced corrosion common in marine environments. The lost-wax casting method and surface polish create a dense, smooth finish that sheds salt and grime more easily than rougher castings. Together these features help prolong appearance and function in humid, salty conditions.

• Material: AISI 316 stainless steel for marine corrosion resistance
• Surface: polished finish from lost-wax process reduces crevices
• Fastener holes: sized for Φ6 bolts to secure hardware tightly

What are the size and installation specifics I need to know?

The filler is sized for a 1-1/2" (38mm) outer diameter opening and measures 84mm (3.31 inches) in overall height, making it suitable for most small-boat or caravan fuel installations. The top plate has a 74mm (2.91 inches) diameter and unscrews for access, while a pull-out lug allows easy removal without tools. Install using Φ6 fasteners through the mounting holes to anchor it firmly to the deck or hull surface.

• Cutout fit: 1-1/2" (38mm) outer diameter
• Overall height: 84mm (3.31 inches)
• Top plate diameter: 74mm (2.91 inches) with pull-out lug
• Fastener size: Φ6 for secure mounting

How does the keyless cap and safety chain improve everyday use?

The keyless cap removes the need to carry a separate key while still providing a secure screw-off closure that resists accidental opening. The pull-out lug built into the cap offers leverage so the cap can be unscrewed quickly, even with gloved hands or in rough conditions. A safety chain keeps the cap attached to the filler to prevent loss during refueling and reduces the risk of dropping the cap overboard.

• Keyless screw-off cap for quick access
• Pull-out lug improves grip and removal ease
• Safety chain prevents cap loss during fueling

Will this match the look and durability expected on a yacht or caravan?

The polished finish and clean lines of this NRC&XRC deck fill provide a high-end visual that complements stainless hardware on yachts and well-equipped caravans. The durable 316 stainless construction and precise manufacturing help maintain that appearance over time with routine cleaning and inspection. Its compact size and low-profile top plate allow it to blend into decks while delivering robust fuel access.

• Polished, marine-grade appearance suitable for yachts and caravans
• Compact profile minimizes deck intrusion
• Durable materials and finish for long-term aesthetics

Who is this for: Boat owners, yacht fitters, caravan enthusiasts or marine technicians looking for a compact, corrosion-resistant fuel deck fill with a convenient keyless cap and safety chain. It suits small to medium-sized vessels and mobile fuel installations where reliable, secure fueling hardware and a polished finish are important.
