#12 x #16 Male Reducer Fitting

The #12 x #16 Male Reducer Fitting by FRAGOLA is a critical component for any serious fuel system or hydraulic line upgrade in performance and custom automotive builds. This reducer fitting allows seamless downsizing from larger diameter hoses to smaller diameter connections, enabling precise system configuration in tight engine bays and custom chassis setups. Whether you're fabricating a fuel delivery system for a restomod, building a competition drag car, or upgrading your street machine's plumbing, this fitting bridges incompatible line sizes without compromising flow integrity or structural reliability.

FRAGOLA fittings are engineered from premium aluminum alloy with precision-machined threads that ensure leak-free connections under high pressure and demanding thermal cycling. The #12 to #16 male reducer design features tapered SAE thread geometry that creates a dependable mechanical seal without requiring additional sealant tape, though professional builders often apply PTFE tape for extra assurance on critical fuel systems. At just 0.16 lbs and compact dimensions (3.2 x 1.75 x 6.05 inches), this fitting integrates easily into confined spaces while maintaining the structural integrity required for fuel systems operating at 60+ PSI or hydraulic systems under sustained load.

Mechanics and fabricators building custom fuel systems, turbo supply lines, or brake hydraulic circuits rely on FRAGOLA reducers for their consistent performance across temperature extremes and vibration-intensive engine environments. Installation is straightforward—hand-thread first, then use a wrench to achieve a firm seat without over-torquing, which can strip aluminum threads. This fitting pairs seamlessly with FRAGOLA hoses and adapters, making it ideal for builders who demand modular, upgradeable systems and the peace of mind that comes with mil-spec quality components backing their work.
