Adapt. #6 Flare X 3/8npt Black

The Adapt. #6 Flare X 3/8npt Black adapter fitting is a critical component for custom fuel system builds, oil cooler installations, and high-performance engine bay plumbing. Designed and manufactured by XRP-XTREME RACING PROD., this adapter allows seamless connection between AN-style (JIC) flare fittings and NPT (National Pipe Thread) ports, bridging two of the most common thread standards in racing and modified vehicle applications. Whether you're fabricating a custom fuel line setup, integrating an aftermarket transmission cooler, or routing braided hose through a modern engine bay, this adapter provides reliable port compatibility without requiring additional conversion blocks.

Built to XRP's exacting standards, the Adapt. #6 Flare X 3/8npt Black features a precision-machined aluminum body with a black anodized finish, delivering corrosion resistance and a professional appearance in high-visibility engine compartments. The 3/8" NPT male thread on one end accepts standard NPT ports or adapters, while the AN6 flare connection on the opposite end accommodates -6 braided hose fittings with 37-degree JIC geometry. The compact form factor—measuring 2.7 x 1.25 x 3.75 inches and weighing just 0.06 lbs—ensures minimal installation footprint in tight spaces common to turbo kits, supercharger manifolds, and custom intake manifold ports. XRP's commitment to quality ensures zero leakage under pressure, critical for fuel delivery and cooling system integrity.

Professionals and enthusiasts building LS engine swaps, turbo fuel systems, and competition drag vehicles rely on this adapter to execute clean, reliable plumbing without improvisation or restrictive factory fittings. It's equally essential for vintage muscle car restorations incorporating modern fuel injection, transmission coolers for track use, and oil system modifications on street performance builds. Installation is straightforward—simply apply appropriate thread sealant (PTFE tape or liquid) to the NPT end, torque to specification, and connect your AN hose with standard hose clamps or crimped fittings. Compatibility spans any application requiring AN6-to-3/8npt conversion, making it an indispensable addition to any serious fabricator's or tuner's inventory.
