Inverted Flare Nut 10pk 3/8-24 for 3/16 Line

The ALLSTAR PERFORMANCE Inverted Flare Nut 10pk 3/8-24 for 3/16 Line (ALL 50110) is a precision steel fitting designed for high-pressure fluid line applications where reliable, leak-free connections are critical. These inverted flare male fittings deliver the secure mechanical advantage required in fuel systems, brake lines, and hydraulic circuits where vibration and pressure cycles demand superior holding power.

Each fitting features a 3/8-24 thread size paired with a 3/16-inch hardline connection, making this configuration ideal for tight-tolerance plumbing in racing, performance, and industrial applications. The zinc oxide finish provides corrosion resistance while maintaining consistent performance across temperature cycles. The inverted flare design—where the cone faces inward—creates a superior seal compared to standard flare configurations, reducing leak potential under sustained pressure. The set of 10 fittings means you have backups for repairs, prototype builds, or stocking your shop inventory.

Builders and technicians working with custom fuel systems, brake upgrades, and hydraulic assemblies rely on ALLSTAR PERFORMANCE fittings for their dimensional accuracy and material consistency. Inverted flare nuts are standard in automotive competition, restoration work, and OEM-equivalent repair applications. Whether you're assembling a race fuel cell system or restoring a classic vehicle to original specification, having verified, quality fittings on hand eliminates installation delays and ensures compliance with system requirements.

The 3/8-24 x 3/16 inverted flare nut is a versatile fastener size found across mid-range fuel and brake systems. Steel construction with zinc oxide plating provides both strength and environmental protection without adding weight. This 10-pack format reduces per-unit cost compared to individual purchases while ensuring adequate supply for full system builds or emergency repairs.
