The #6 to 11/16-18 Inv Flare Fitting is a precision hydraulic and pneumatic adapter designed for systems requiring reliable straight-port connections between AN-sized male ports and inverted flare line fittings. Engineered by RUSSELL, a trusted name in fluid power distribution, this fitting serves critical applications in racing fuel systems, brake lines, air suspension setups, and industrial hydraulic assemblies. The straight-adapter configuration eliminates unnecessary bends, reducing pressure drops and turbulence while maintaining system integrity under high-cycle operation.
Constructed from aluminum in a natural (anodized) finish, the #6 to 11/16-18 Inv Flare Fitting combines lightweight durability with corrosion resistance—essential for both underhood and exposed outdoor installations. The 6 AN male port accommodates standard -6 hose and tubing assemblies, while the 11/16-18 inverted flare male connection ensures secure, leak-free sealing with complementary female fittings. Aluminum construction provides a strength-to-weight ratio superior to brass alternatives, and the machined threads guarantee precise fitment and repeatability across production runs. Measuring just 2.5 x 1.65 x 4.85 inches and weighing only 0.06 pounds, this adapter integrates seamlessly into compact manifold layouts without adding bulk.
Performance enthusiasts, fabricators, and fleet maintenance teams rely on RUSSELL adapters to simplify custom plumbing without compromising safety or flow efficiency. This fitting is ideal for retrofit projects where existing 11/16-18 inverted flare line infrastructure must integrate with modern AN-port systems—common in fuel injection upgrades, turbo installations, and brake system overhauls. Installation is straightforward: hand-tighten first, then use a wrench to snug the connection while supporting the body to prevent cross-threading. Pair this adapter with compatible hose, fittings, and sealing tape to build leak-free circuits rated for your system's pressure specification.
