#3 Male - 7/16-24 Female Inverted Flare Fitting

The #3 Male - 7/16-24 Female Inverted Flare Fitting from XRP-XTREME RACING PROD. is a precision adapter designed for high-performance fuel and fluid delivery systems in custom automotive builds. This straight fitting bridges the gap between different hose standards, allowing builders and mechanics to integrate legacy hardline components with modern AN (Army-Navy) line specifications. Whether you're restoring a classic race engine, upgrading fuel delivery on a turbocharged platform, or fabricating custom brake and fuel lines for a ground-up build, this adapter ensures leak-free connections under demanding conditions.

Manufactured from nickel-plated steel, the #3 Male - 7/16-24 Female Inverted Flare Fitting delivers durability and corrosion resistance in engine bays and fuel system environments. The inverted flare design—a proven standard in automotive hydraulic and fuel systems—creates a robust seal by compressing the flare cone against the fitting's conical seat, eliminating the risk of separation under vibration or pressure cycling. The 1/4-inch hardline compatibility and steel construction mean this adapter handles both standard fuel system pressures and the elevated demands of fuel-injection upgrades, forced induction setups, and nitrous oxide systems. The nickel plating protects against rust and provides a clean appearance in visible installations.

This adapter is essential for mechanics and fabricators working on fuel system retrofits, custom hardline routing, and performance engine conversions where AN male ports must connect to 7/16-24 female inverted flare components. It accommodates 1/4-inch hardline tubing and works seamlessly with carburetor fuel bowls, mechanical fuel pumps, and vintage fuel distribution blocks that use inverted flare connections. Installation requires basic hose crimping and fitting tools; ensure proper flare geometry on hardline ends for a watertight seal. The lightweight design—just 0.17 lbs—integrates cleanly into tight engine compartments without adding bulk, making it ideal for vintage restorations, Pro Street builds, and street rod fuel system upgrades.
