8AN to M16x1.5 AN/JIC Flare Inverted

The REDHORSE PERFORMANCE 8AN to M16x1.5 AN/JIC Flare Inverted adapter is a precision hydraulic and fuel line connector designed for high-performance automotive, marine, and industrial fluid transfer systems. This straight adapter fitting transitions 8 AN male connections to M16x1.5 inverted flare male ports, enabling seamless integration between systems using different standardized connection formats.

Constructed from aluminum and finished in black anodized coating, this 8161-series fitting provides corrosion resistance and durability in demanding environments. The inverted flare design creates a reliable mechanical seal suited to fuel injection systems, transmission coolers, and custom hydraulic assemblies where AN and JIC standards converge. The compact profile—measuring 2.75 × 1.1 × 3.8 inches and weighing just 0.08 pounds—minimizes installation footprint without compromising structural integrity or flow characteristics.

This adapter serves automotive enthusiasts performing engine swaps, fabricators building custom fuel systems, and technicians maintaining marine propulsion equipment. It is commonly specified in hot rod fuel line assemblies, supercharger manifold systems, and industrial flow circuits where AN fittings interface with factory or aftermarket M16×1.5 ports. Compatibility depends on confirming both male threads are accessible and not obstructed by surrounding components.

AN (Army-Navy) and JIC (Joint Industry Council) standards remain industry-wide benchmarks for fluid system reliability. AN sizing designates nominal hose inside diameter in eighths of an inch—8AN equals 1 inch ID—while inverted flare geometry ensures sealing pressure is applied consistently across the connection shoulder, critical for systems operating under temperature and vibration cycling.
