Straight Adapter Fitting #10 x 3/8 MPT

The FRAGOLA Straight Adapter Fitting #10 x 3/8 MPT (part number 481611) is a precision hydraulic and pneumatic adapter designed to connect AN-sized male fittings to NPT male ports. Constructed from aluminum and finished in blue anodize, this straight adapter enables reliable fluid transfer in high-pressure systems where AN and NPT threads must interface.

The #10 AN male end accepts standard -10 AN fittings common in fuel, coolant, and brake line applications, while the 3/8-inch NPT male port threads into female NPT receivers. The straight configuration—as opposed to 45° or 90° angles—simplifies installation in tight spaces and reduces system complexity. Blue anodizing provides corrosion resistance and thermal stability, essential for systems exposed to moisture, temperature cycling, or salt environments. Weighing just 0.06 pounds, this adapter adds minimal weight while maintaining the structural integrity required for pressurized duty.

This adapter serves motorsports, marine, aerospace, and industrial hydraulic applications where AN and NPT standards must coexist within the same system. Common scenarios include fuel delivery systems, brake line circuits, coolant loops, and pneumatic control manifolds. Systems requiring mixed thread standards benefit from FRAGOLA's precision engineering and material selection, which ensure leak-free performance under sustained pressure and vibration.

FRAGOLA adapters are engineered to SAE and ISO specifications, making them suitable for both OEM replacement and aftermarket system construction. The straight design minimizes pressure drop and turbulence compared to angled fittings, an advantage in closed-loop systems where efficiency matters. This is a single-unit adapter—order the quantity needed for your manifold, fuel rail, or hydraulic bank configuration.
