#10 Male to 3/8in NPT Ano-Tuff Adapter

The EARLS #10 Male to 3/8in NPT Anodized Aluminum Adapter is a straight-port fitting designed to bridge 10 AN male ports to 3/8-inch NPT male connections. This is a single-unit adapter engineered for hydraulic and pneumatic systems where AN and NPT thread standards must interface. The black anodized aluminum construction provides corrosion resistance while maintaining a lightweight profile suitable for motorsports, aerospace, industrial, and high-performance automotive applications.

Aluminum adapters like this offer significant advantages over steel alternatives in weight-sensitive applications. The 10 AN thread (0.625-18 UNF) is a high-flow standard commonly used in fuel delivery, oil cooling, and transmission cooler circuits, while 3/8-inch NPT is the industrial plumbing standard found on many component ports and manifold inlets. The anodized finish adds a protective oxide layer that resists oxidation and minor corrosion, making this adapter reliable in engine bays and exposed mounting positions. Straight-port geometry ensures minimal flow disruption and turbulence at the connection point.

This adapter serves technicians and builders who need to connect legacy NPT-threaded components to modern AN-equipped systems, or vice versa. Common applications include retrofitting fuel systems, integrating aftermarket coolers into stock NPT ports, adapting gauge manifolds, or consolidating mixed-thread hydraulic networks. The compact 1.6 x 1 x 3-inch footprint fits tight engine compartments. This is a single-unit sale, so verify your system's thread requirements and flow rate before ordering.
