Inverted Flare Nut 50pk 3/8-24 for 3/16 Line

The Inverted Flare Nut 50pk 3/8-24 for 3/16 Line from ALLSTAR PERFORMANCE is an essential component for builders, mechanics, and motorsports professionals who demand reliability in brake and fuel line connections. These inverted flare fittings are engineered to create leak-proof seals on hardline tubing, making them indispensable for high-performance engines, street rods, race cars, and hydraulic systems. The 50-pack quantity ensures you have spares on hand for multiple projects or future builds.

Constructed from durable steel with a zinc oxide finish, each nut features a 3/8-24 thread size designed to accommodate 3/16-inch hardline tubing. The inverted flare design—where the male flare cone is reversed—provides superior grip and a more secure connection than standard flare fittings, particularly under vibration and pressure cycling. Zinc oxide plating resists corrosion while maintaining easy installation and removal, critical for both initial assembly and future maintenance or replacement scenarios.

Whether you're assembling a custom brake system, connecting fuel lines on a classic car restoration, or fabricating a performance hydraulic circuit, these fittings deliver OEM-quality performance at a competitive price point. The 50-pack format makes bulk ordering economical for shops, race teams, and serious enthusiasts who work with multiple vehicles. Installation is straightforward: simply flare your 3/16-inch tubing to spec, thread onto a matching male inverted flare fitting, and tighten with a wrench—no special tools required.
