Brass Fuel Hose Connector 1/4" NPT – Available in 3 Sizes

This brass 1/4" NPT fuel hose connector is engineered for maximum reliability in your boat’s fuel system. Its precision-cast brass body resists corrosion in marine environments and delivers long-lasting performance.

Applications & Variants:

• Ø6.35 mm Barb (Code 03847-1): Ideal for small boats (~3–5 m) and lower horsepower outboard engines. This size suits narrow fuel lines and provides sufficient fuel flow for dinghies, inflatables, and small motorboats up to around 30 HP.
• Ø7.9 mm Barb (Code 03847-2): A versatile medium size for mid-sized boats (~5–7 m) and mid-range engines. It offers higher flow capacity, perfect for fuel lines on boats with 50–100 HP or for vessels undertaking longer trips where consistent fuel delivery is key.
• Ø10 mm Barb (Code 03847-3): The largest option recommended for bigger vessels (7+ m) or dual-engine setups requiring high fuel throughput. This variant accommodates powerful outboards (100+ HP) or inboard engines, ensuring maximum fuel flow with no starvation at full throttle.

Installation is straightforward: apply thread sealant (e.g., PTFE tape) to the 1/4" NPT male thread and screw it securely into the port. Attach your fuel hose to the barbed end and clamp it for a leak-proof fit. The brass fuel hose connector 1/4" NPT provides a dependable, vibration-resistant junction that prevents leaks and withstands the harsh marine conditions. It’s an essential upgrade for anyone looking to improve or repair their boat’s fuel system with a professional-grade fitting.
