Brake Adapter -3 to 7/16 -24 I.F.

The Brake Adapter -3 to 7/16 -24 I.F. by EARLS is a precision fitting engineered for hydraulic and pneumatic brake systems that require seamless conversion between AN (Army-Navy) male threads and inverted flare female connections. This straight adapter serves fuel, oil, coolant, and brake line applications where standard metric or SAE fittings don't match existing hardline infrastructure. Whether you're custom-building a classic hot rod brake system, retrofitting a performance vehicle, or servicing industrial hydraulic equipment, this adapter bridges connection gaps without sacrificing flow integrity or safety.

Manufactured from steel and finished with zinc plating for corrosion resistance, this adapter features a 3 AN male thread on one end and a 7/16-24 inverted flare female port on the other, accommodating 1/4-inch hardline tubing. The inverted flare connection method—also called JIC or ISO 6149—provides reliable leak-free sealing under high pressure and vibration, making it ideal for underhood brake applications where reliability is non-negotiable. The compact 1.1 x 1.05 x 2.95-inch form factor and minimal 0.07-pound weight ensure easy installation in tight engine bays without adding bulk or weight penalty.

Technicians, fabricators, and enthusiasts working on custom brake circuits, fuel distribution systems, and hydraulic assemblies will appreciate this adapter's ability to unify disparate fitting standards on a single platform. Installation is straightforward: hand-thread the 3 AN male end into your system component, then connect the inverted flare female side to your 7/16-24 hardline with a standard brake line wrench—no special tools required. EARLS adapters are trusted across racing, street-rod, and professional shop environments for their dimensional accuracy and consistent performance.
