Inverted Flare Nut 10pk 7/16-24 for 1/4 Line S/S

The Inverted Flare Nut 10pk 7/16-24 for 1/4 Line S/S from ALLSTAR PERFORMANCE is an essential component for professional mechanics and serious automotive enthusiasts building or maintaining high-performance fuel systems, brake lines, and hydraulic circuits. Inverted flare fittings are the industry standard for automotive applications because they create a stronger, more reliable seal than straight-thread connections—critical when pressurized fluid delivery is non-negotiable. This 10-pack stainless steel configuration delivers the exact hardware you need for a complete fuel system overhaul, engine bay plumbing upgrade, or brake line replacement without purchasing oversized bulk quantities.

The 7/16-24 thread specification and 1/4-inch line compatibility represent the most common sizing for domestic muscle cars, modern performance vehicles, and race engine builds where precision hydraulic fitment matters. Stainless steel construction resists corrosion and vibration-induced loosening far better than zinc-plated steel, extending the service life of your fuel or brake system in both street and competition environments. The inverted design—where the flare cone seats against a matching cone inside the body—distributes pressure more evenly across the contact surface, reducing stress concentration and lowering failure risk under sustained high fuel pressure or repeated brake cycling.

Whether you're rebuilding a vintage hot rod fuel system, upgrading brake lines on a track-focused street car, or assembling a fuel injection setup from the ground up, these stainless inverted flare nuts integrate seamlessly with standard automotive flare-nut wrenches and match OEM and aftermarket fuel rails, carburetors, and hydraulic components. Installation is straightforward: hand-thread onto prepared 1/4-inch lines (using a flaring tool to create the matching inverted cone), then torque to specification with a flare-nut wrench to avoid rounding. ALLSTAR PERFORMANCE's reputation for precision fitment ensures these nuts thread smoothly and seat consistently across the entire 10-pack, eliminating the frustration of mismatched or marginal hardware.
