Reducer AN Male -12 to -16

The ALLSTAR PERFORMANCE Reducer AN Male -12 to -16 is a straight-port AN adapter fitting designed to connect high-pressure hydraulic or pneumatic lines of different nominal sizes. This aluminum-bodied reducer transitions from a -16 AN male port down to a -12 AN male configuration, allowing system designers and technicians to integrate components with mismatched port sizes without sacrificing flow integrity or system pressure rating.

Built from aluminum and finished in black anodize, this adapter combines light weight with corrosion resistance—a practical advantage in environments exposed to moisture or salt spray where steel fittings would degrade. The straight-port design ensures minimal turbulence and pressure drop across the fitting, critical in closed-loop hydraulic systems where restriction can trigger heat buildup or cavitation. The -12 and -16 AN designations follow SAE J518 aerospace standards, ensuring compatibility across OEM and aftermarket component networks. Weighing just 0.16 lbs, the compact 4 x 1.55 x 4.2-inch form factor fits tight engine bays and frame rails without adding measurable system weight.

This reducer serves motorsports builders, aircraft maintenance, agricultural equipment restoration, and industrial hydraulic fabricators who need reliable port-size transitions. It's especially valuable in custom fuel systems, brake line upgrades, and power steering installations where a single source must feed multiple sub-systems. Each unit ships individually, allowing buyers to stock exact quantities for specific builds rather than purchasing full kits.

AN fittings remain the standard across high-performance and aviation applications because their reusable design, consistent thread pitch, and color-coded identification reduce assembly errors and streamline diagnostics. The -12 to -16 step-down ratio is common in applications where a main feed line (larger diameter, lower velocity) branches into multiple smaller circuits (higher velocity, tighter tolerances).
