#10 x #12 Male Reducer Fitting

The FRAGOLA #10 x #12 Male Reducer Fitting (MPN 491920) is a straight-port adapter designed to connect AN-sized hydraulic and fluid transfer lines with precision and reliability. This aluminum reducer fitting transitions from a #12 AN male port to a #10 AN male port, making it essential for custom plumbing applications in performance vehicles, race cars, marine systems, and hydraulic installations where space constraints or existing line configurations demand a stepped-down connection.

Constructed from lightweight aluminum and finished in blue anodize, this fitting delivers corrosion resistance and visual identification of line function in complex hydraulic layouts. The male-to-male configuration allows direct port-to-port connection without requiring additional adapter elbows or manifold blocks. AN standard fittings maintain concentricity and flow characteristics critical for fuel delivery, coolant circulation, and high-pressure brake or power steering lines. The blue anodized finish provides both protection against oxidation and clear differentiation from -12 and -10 line sizes in multi-circuit systems.

This reducer is ideal for builders working with custom fuel systems, turbo intercooler plumbing, transmission cooler lines, and marine engine cooling circuits where downsizing from larger to smaller lines improves flow distribution or accommodates existing port configurations. Serious fabricators and restoration shops rely on FRAGOLA adapter fittings to maintain system integrity while adapting between different AN sizes. The lightweight aluminum construction keeps systems lean without sacrificing durability in moderate-pressure applications.

Each fitting ships as a single unit, ready for immediate installation. Confirm your system pressure rating and hose compatibility before use to ensure safe operation. Pair with appropriate sealing tape or thread sealant at fitting ports for leak-free connections in your custom plumbing assembly.
