Hose Fitting #16 45 Deg. to #12 Hose Black

The Hose Fitting #16 45 Deg. to #12 Hose Black is a precision adapter designed for custom fuel, oil, and coolant systems where space and angle constraints demand a stepped reduction fitting. Built by FRAGOLA, a trusted name in high-performance plumbing for street rods, race cars, and engine swaps, this 45-degree elbow bridges two different hose sizes in a single compact component. Whether you're routing lines around tight engine bay obstacles or building a custom fuel system for a carbureted build, this fitting eliminates the need for multiple adapters and reduces leak points in your system.

Manufactured from black-anodized aluminum, the Hose Fitting #16 45 Deg. to #12 Hose Black delivers strength while resisting corrosion in engine bay environments. The 45-degree angle design allows you to redirect hose runs without kinking or crushing, maintaining consistent flow velocity and reducing turbulence in fuel and fluid delivery systems. The #16 inlet accepts larger diameter hose stock, while the #12 outlet steps down for applications where space or system requirements demand a smaller connection—a common requirement in vintage restorations and tight-quarters engine builds. FRAGOLA's proven hose fitting specification ensures SAE or JIC port compatibility, critical for reliable pressure containment in fuel injection, forced induction, and supercharger plumbing applications.

This fitting excels in custom fuel systems, oil cooler installations, and intercooler piping where angled adapters prevent kinks that restrict flow or weaken hose integrity. Mechanics and fabricators working on LS swaps, vintage Mopar conversions, and turbocharged builds rely on stepped fittings like this to navigate complex underhood layouts while maintaining system reliability. Installation is straightforward—simply slide hose onto each barbed end, secure with quality hose clamps, and verify all connections are leak-free under pressure. The compact dimensions (5.35 x 1.7 x 8.05 inches) and lightweight design (0.375 lbs) make it ideal for weight-conscious performance builds where every ounce matters.
