Hose Barb to AN Adapter Fitting

Upgrade your fuel system with ease using our Hose Barb to AN Adapter Fittings – the perfect solution for converting traditional rubber hose to high-performance AN-style plumbing. Whether you're upgrading your fuel system, retrofitting an LS swap, or enhancing any custom plumbing job, these fittings provide a reliable bridge between rubber lines and AN components.

Why Use a Hose Barb to AN Adapter?

Many factory or older-style fuel systems use standard rubber hose, which isn’t always compatible with modern AN-style components or PTFE-lined hose systems. Our Hose Barb to AN adapters allow you to adapt those legacy rubber lines to a modern AN system for better reliability, upgrade potential, and performance.

• Compatible with standard rubber fuel hose
• Converts to male AN fitting for PTFE or braided hose use
• Easy installation for fuel systems, coolant lines, and more
• Multiple sizes available to fit your setup

Important Note on Pressure Ratings

While our adapters are rated for high performance, it’s critical to understand that rubber hose has limited pressure tolerance compared to PTFE or braided AN hose systems. These adapters enable the transition, but the pressure capacity of your plumbing system will ultimately depend on the weakest component – often the rubber hose itself.

Ensure all components you select are appropriate for the pressure requirements of your project, especially when building fuel systems for EFI swaps or performance builds.
