6AN Male Flare to M14x1.5 Inverted Adapter

The 6AN Male Flare to M14x1.5 Inverted Adapter by REDHORSE PERFORMANCE is a precision hydraulic and fuel line fitting designed for high-performance automotive and motorsports applications. This straight adapter bridges two common industrial standards, allowing technicians and builders to connect SAE 6AN male flare lines to M14x1.5 inverted flare ports found on engines, fuel systems, and custom fabrication projects. Whether you're upgrading fuel delivery on a turbocharged engine, installing aftermarket cooling systems, or integrating European metric components into a domestic platform, this adapter eliminates the need for custom fabrication or multiple fittings.

Manufactured from aluminum and finished in blue anodizing, this fitting combines corrosion resistance with lightweight construction—critical for performance-focused builds where every fraction of a pound matters. The blue anodized finish not only provides visual identification within complex plumbing systems but also protects against oxidation in harsh engine bay environments. The inverted flare design on the M14x1.5 side accommodates metric European specifications, while the 6AN male flare end maintains compatibility with standard North American SAE hydraulic and fuel line systems. The straight configuration ensures minimal turbulence and pressure drop, maintaining system efficiency and reliability under demanding operating conditions.

This adapter is ideal for engine swaps mixing metric and SAE components, EFI fuel system conversions, custom radiator and intercooler installations, and any application requiring secure metric-to-SAE connections. Installation is straightforward—hand-tighten first, then torque to manufacturer specifications using two wrenches to prevent line rotation. The lightweight 0.055 lb design means virtually no added mass, and the compact 2.8 × 1.1 × 3.85 inch footprint fits tight engine bay configurations. Technicians and enthusiasts consistently rely on REDHORSE PERFORMANCE adapters for leak-free performance connections that survive high-pressure cycles and temperature extremes.
