Inverted Flare Nut 2pk 1/2-20 for 3/16 Line

The Inverted Flare Nut 2pk 1/2-20 for 3/16 Line is an essential fastening component for precision brake and fuel line connections in high-performance automotive builds. Manufactured by ALLSTAR PERFORMANCE, this two-piece set addresses a critical need in custom engine bay work: creating leak-proof, vibration-resistant connections where standard hardware fails. Whether you're upgrading brake systems on a street rod, installing aftermarket fuel delivery on a modified engine, or rebuilding a competition vehicle, these inverted flare nuts deliver the reliability that separates professional-grade work from amateur installations.

Inverted flare design creates a superior seal compared to standard compression fittings by forcing the tubing end to form a 45-degree cone that locks securely into the matching nut seat. The 1/2-20 thread pitch ensures compatibility with common brake and fuel line banjo bolts and hardline adapters found on performance platforms, while the 3/16-inch line size handles flow requirements for both hydraulic braking circuits and fuel injection systems. The two-pack format accommodates typical dual-line installations, reducing trips for additional hardware and ensuring consistent fitment across your build. ALLSTAR PERFORMANCE's engineering guarantees dimensional accuracy and consistent thread quality, eliminating the stripped or leaking connections that plague inferior alternatives.

Mechanics and fabricators trust this product for brake system upgrades, fuel system relocations, and custom hardline routing on everything from carbureted engines to modern EFI conversions. Installation requires a wrench and basic line-bending skills—no special tools needed. Compatible with any SAE-spec 3/16-inch brake or fuel tubing, these nuts work seamlessly with both steel and stainless hardlines. Keep a pair on the shelf for emergency repairs or stock them for bulk fabrication projects; at just 0.08 lbs per pair, storage is never an issue.
