Inverted Flare Nut 2pk 7/16-24 for 3/16 Line

The Inverted Flare Nut 2pk 7/16-24 for 3/16 Line by ALLSTAR PERFORMANCE is an essential brake and fuel line coupling component for high-performance and custom automotive builds. These precision-engineered fittings are designed for mechanics and fabricators who demand reliability in critical hydraulic and fuel system applications. Whether you're assembling a custom street rod, upgrading brake lines on a race car, or restoring a classic vehicle, inverted flare nuts provide a leak-free, vibration-resistant connection that withstands extreme pressure and temperature cycling.

This two-pack features a 7/16-24 thread pitch, which is the industry standard for SAE inverted flare connections used in automotive fuel and brake systems. The inverted design—where the flare faces inward—creates a superior sealing surface compared to standard flare nuts, reducing the risk of seepage under pressure. The 3/16-inch line size accommodates mid-range fuel and brake system applications, making these fittings versatile across most carbureted and fuel-injected platforms. ALLSTAR PERFORMANCE's manufacturing tolerances ensure consistent thread engagement and flare compatibility, critical factors when precision matters under load.

Professional mechanics, hot rod builders, and DIY enthusiasts benefit most from keeping spare inverted flare nuts on hand during system repairs, modifications, or emergency roadside adjustments. These fittings work seamlessly with DOT-approved brake lines, carburetor fuel systems, and modern fuel injection setups that require SAE inverted flare connections. Installation is straightforward—thread onto pre-flared line ends with a wrench, ensuring the flare sits flush and the nut seats firmly without over-tightening, which can damage both nut and fitting. The compact 2pk format makes replacement quick and cost-effective for single repairs or system overhauls.
