#10 Male to #8 Male Port Ano-Tuff Adapter

The #10 Male to #8 Male Port Ano-Tuff Adapter from EARLS is an essential hydraulic fitting for custom cooling and fuel system builds where port size reduction is required. Whether you're installing an upgraded radiator, intercooler, or fuel pressure regulator in a modified engine bay, this adapter bridges the gap between incompatible AN port sizes with precision engineering. Fabricators, performance shops, and weekend warriors rely on EARLS adapters to simplify complex plumbing layouts without sacrificing reliability or flow integrity.

Machined from aluminum and finished with EARLS' proven Ano-Tuff anodized coating, this adapter resists corrosion and oxidation in engine compartments exposed to heat cycles, moisture, and road salt. The male-to-male configuration allows direct hose coupling on both ends, eliminating the need for separate fittings and reducing joint count—a critical detail when reducing pressure drop across fuel rails or coolant circuits in turbocharged and supercharged applications. The compact 1.7 x 1.05 x 2.6-inch form factor fits tight engine bays where space is at a premium, and the lightweight 0.06-pound design keeps weight savings intact in chassis builds.

This adapter is ideal for builders transitioning between OEM and aftermarket component sizes, or when consolidating multiple smaller-diameter feeds into a single larger line for better pressure regulation. Common applications include intercooler outlet-to-radiator inlet transitions, fuel cell feed-line configurations, and custom coolant bypass circuits. Verify your existing hose barb or fitting thread spec before ordering, as AN port sizing is not universal across all manufacturers—cross-referencing with your component documentation ensures first-time fitment and eliminates costly rework during final assembly.
