#3 x 9/16-18 I.F. Brake Adapter Fitting - Steel

The #3 x 9/16-18 I.F. Brake Adapter Fitting from FRAGOLA is a precision steel adapter designed for high-performance brake line systems and hydraulic brake applications. This straight adapter fitting converts between AN (Army-Navy) and inverted flare male connections, making it essential for custom brake system installations, restoration projects, and performance vehicle builds. Whether you're upgrading a classic hot rod, modernizing vintage braking systems, or assembling a competition-grade hydraulic brake circuit, this adapter bridges connection standards that would otherwise be incompatible.

Engineered from durable steel with a zinc oxide finish, the #3 x 9/16-18 I.F. Brake Adapter Fitting delivers corrosion resistance and reliable sealing under demanding hydraulic pressures. The adapter features a 3 AN male connection on one end and a 9/16-18 inch inverted flare male connection on the other, allowing seamless integration with 1/4-inch hardline tubing and standard brake components. The straight design minimizes flow restriction and turbulence, which is critical for maintaining consistent brake feel and responsiveness. FRAGOLA's precision threading and manufacturing tolerances ensure leak-free performance and easy hand-tight installation without specialized adapters.

Technicians and enthusiasts rely on this fitting for brake system modifications where standard connections don't align. It's commonly used in custom brake line assemblies, master cylinder retrofits, and proportioning valve installations on street rods, race cars, and restored vehicles. The compact design (2.85 x 0.75 x 3.25 inches) fits tight engine bays and chassis configurations without interfering with other components. For anyone fabricating or repairing hydraulic brake systems where AN and inverted flare standards must meet, this FRAGOLA adapter provides the robust, leak-proof solution demanded by both street and competition applications.
