#12 x #16 Male Reducer Black

The #12 x #16 Male Reducer Black is a precision hose adapter engineered for custom fuel, coolant, and hydraulic system applications in modified vehicles and high-performance builds. This fitting bridges two different AN port sizes, allowing mechanics and enthusiasts to transition from larger to smaller diameter hose runs without custom fabrication. Whether you're building a fuel system for a turbocharged engine, installing a custom coolant loop, or rerouting hydraulic lines in a race car, a quality reducer fitting is essential for maintaining system integrity and preventing leaks that can compromise engine reliability.

Built by FRAGOLA, a trusted name in automotive fluid transfer systems, this male reducer features precision-machined construction and anodized black finish for corrosion resistance and a professional appearance in engine bays. The #12 to #16 step-down ratio accommodates standard AN hose sizing, with the male fitting design allowing direct connection to female ports on fuel rails, manifolds, block fittings, and aftermarket components. Black anodizing protects against oxidation in harsh underhood environments, while the compact 2.05 x 1.85 x 4.05-inch profile fits tight spaces common in modified engine compartments. At just 0.16 pounds, the fitting adds minimal weight while delivering the thread accuracy and seal integrity that prevent catastrophic fuel or coolant loss during high-boost operation.

This reducer serves builders who demand reliability in street machines, drag cars, and road-course vehicles where vibration, temperature cycling, and pressure spikes stress every connection. Installation requires proper thread-sealing compound and torque to specification—critical steps that prevent system failures during boost or high-RPM operation. The black finish integrates seamlessly into modern underhood aesthetics while the male configuration simplifies integration into existing manifold ports and fuel system architectures. Verify your specific AN port configuration and hose sizes before ordering to ensure correct fitment in your custom fuel, coolant, or hydraulic system.
