Why Use an AN Reducer Adapter?

Different components in a fuel or fluid system often require different AN fitting sizes. A reducer adapter allows builders to safely transition between larger feed lines and smaller component ports without compromising reliability or serviceability.

Translation: fewer sketchy adapters stacked together like mechanical Jenga.

Size: The right is a feminine AN10 to male AN6. The thread size of the 10AN is 7/8-14 UNF. The thread size of the 6AN is nine/16-18 UNF.

Parameter: The utmost working pressure is 1,500 PSI. The temperature vary is -40°F to 250°F.

Common Applications

• EFI fuel systems
• Return-style fuel setups
• Fuel pressure regulator plumbing
• Turbocharger oil feed and return systems
• Oil cooler routing
• Transmission cooler systems
• LS swap fuel systems
• Drift and race car plumbing
• Custom AN fluid routing projects

Subject matter: The right is product of aluminum alloy 6061-T6 with a black anodized surface.

Perfect for Custom Fuel System Builds

Large feed lines such as 10AN are commonly used for high-flow fuel delivery, while smaller 6AN ports are often found on regulators, fuel rails, filters, and auxiliary components. These reducers help bridge the gap cleanly and safely.

Especially useful when your fuel system now resembles commercial irrigation equipment.

High-Flow Billet Design

The precision-machined billet aluminum construction maintains strong durability while minimizing restriction and maintaining proper flow characteristics under high-pressure conditions.

Because fuel starvation at full boost tends to become very expensive immediately.

Sealing: The AN aspect is sealed at a 37-degree attitude.
Application: The right is widely utilized in fuel systems, cooling systems, LS swaps, and more.

Compact and Lightweight

The compact reducer body simplifies installation in tight engine bays and custom plumbing layouts while resisting corrosion from gasoline, E85, methanol, race fuel, oil, coolant, and transmission fluid exposure.

Translation: your engine bay looks cleaner and leaks less. Everybody wins.

Built for Modern Performance Systems

Compatible with modern AN plumbing and braided hose systems, these reducers support the demands of turbocharged, supercharged, E85, and motorsports applications where proper fluid delivery matters.

Because “it probably has enough fuel” is not a tuning strategy.
