Straight Adapter Fitting #10 x 1/2 MPT

The FRAGOLA Straight Adapter Fitting #10 x 1/2 MPT (part number 481610) is a precision-engineered AN-to-NPT adapter designed for hydraulic and fuel system applications requiring reliable, leak-free connections. This straight adapter converts a #10 AN male port to a 1/2-inch NPT male port, enabling seamless integration between AN-based high-pressure systems and standard pipe-threaded fittings commonly found in industrial, automotive, and marine hydraulic setups.

Constructed from aluminum with blue anodized finish, this adapter combines weight savings with corrosion resistance—critical for environments exposed to moisture, salt air, or aggressive hydraulic fluids. The #10 AN designation corresponds to a 5/8-inch hose size, while the 1/2-inch NPT connection accommodates standard industrial male pipe threads. The straight (non-45°, non-90°) configuration minimizes flow disruption and installation complexity in space-constrained applications. Anodizing provides protection against oxidation and extends service life, particularly in coastal or humid installations where uncoated aluminum would degrade rapidly.

This fitting serves custom hydraulic builds, fuel cell installations, marine engine conversions, off-road recovery systems, and industrial equipment upgrades where AN and NPT ports must be bridged without adapting multiple fittings. Technicians and fabricators rely on FRAGOLA adapters for predictable performance under pressure—critical in applications where connection failure risks fluid loss, system damage, or safety hazards. The compact 1.65 x 1.2 x 4-inch dimensions and 0.07-pound weight make installation straightforward in tight engine bays or component clusters.
