Adapter 90 #6 Flare 1/2in NPT

The Adapter 90 #6 Flare 1/2in NPT is an essential marine plumbing fitting for anglers and boaters who demand reliable, leak-free connections in their fuel, water, and hydraulic systems. This 90-degree adapter bridges two critical port sizes—a #6 AN (Army Navy) male flare connection and a 1/2-inch NPT (National Pipe Thread) male port—making it indispensable for custom rigging, engine fuel lines, and freshwater system installations on vessels ranging from center consoles to offshore sportfishers. Built to meet the exacting standards of professional marine mechanics and serious DIY boat builders, this fitting eliminates the guesswork and safety risks associated with improper hose routing or incompatible connections.

Machined from lightweight aluminum and finished in blue anodized coating, the Adapter 90 #6 Flare 1/2in NPT resists corrosion and saltwater degradation while maintaining structural integrity under pressure cycles. The 90-degree orientation is critical for tight engine compartments and bilge spaces where straight fittings create installation conflicts or dangerous kinks in fuel or coolant lines. The #6 AN flare design uses a 37-degree JIC (Joint Industry Council) cone seal, proven in aviation and marine applications for superior hold without thread sealant tape, while the 1/2-inch NPT side accepts standard threaded ports on most marine manifolds, carburetors, and auxiliary systems. At just 0.1 lbs and measuring 2.85 x 0.9 x 4.65 inches, it fits into compact spaces without adding dead weight to your vessel's systems.

Boaters upgrading fuel management, installing custom cooling loops, or transitioning between legacy NPT plumbing and modern AN hose assemblies will appreciate the precision engineering of this A-1 Products adapter. Installation requires only standard wrenches—no thread tape on the flare side—and delivers a permanent, vibration-resistant connection that won't weep or fail under the thermal cycling and pressure spikes of high-performance marine engines. Whether you're rebuilding a twin-engine offshore rig, adding redundant fuel tanks, or retrofitting a cabin cruiser's galley water system, the Adapter 90 #6 Flare 1/2in NPT ensures code-compliant, professional-grade results that pass insurance and Coast Guard inspections.
