Female -6AN to Male -10AN Adapter Fitting

The female -6AN to male -10AN adapter fitting is a critical component in hydraulic and fuel line systems where port size transition is necessary. Designed for professionals and enthusiasts working with high-performance engines, racing fuel systems, and custom hydraulic builds, this straight adapter enables seamless connection between smaller -6AN female ports and larger -10AN male ports. Its compact, lightweight design makes it ideal for tight engine bay installations and systems where space efficiency matters.

Constructed from aluminum and finished with black anodized coating, this adapter delivers both corrosion resistance and durability in demanding environments. The anodized surface protects against oxidation while maintaining a professional appearance in custom builds. The straight configuration ensures direct, leak-free connections without complex routing, and the precision-engineered threads guarantee a secure seal when used with appropriate hose fittings or line adapters. The aluminum construction keeps overall system weight minimal—critical in performance applications where every fraction of a pound affects acceleration and handling.

This adapter is essential for builders integrating components from different manufacturers or upgrading fuel delivery and cooling systems. Mechanics and fabricators rely on sizing adapters like this when working with turbo systems, nitrous applications, or custom radiator setups that require mixed port sizes. The fitting works with standard -6AN and -10AN hose assemblies and fittings commonly found in motorsports and industrial fluid transfer applications. Installation requires only a wrench and basic plumbing knowledge, making it accessible for both professional shops and experienced DIY builders.
