Hose Fitting #16 Str. to #12 Hose Black

The Hose Fitting #16 Str. to #12 Hose Black from FRAGOLA is a precision straight adapter designed for high-pressure fuel, oil, and coolant systems in performance automotive applications. This fitting bridges the gap between 16 AN female ports and 12 AN hose connections, making it essential for custom fuel system builds, engine bay modifications, and transmission cooler installations. Whether you're upgrading a carburetor fuel line, routing an oil cooler circuit, or integrating auxiliary cooling systems, this adapter provides the secure, leak-free connection your build demands.

Constructed from lightweight aluminum with black anodized finish, the Hose Fitting #16 Str. to #12 Hose Black resists corrosion and maintains a professional appearance in engine bays. The straight-flow design minimizes turbulence and pressure loss compared to 90-degree adapters, critical when fuel or oil pressures are already constrained by filter size or pump output. FRAGOLA's Pro-Flow 2000 Series fittings feature JIC-compliant threads and hose barb geometry that delivers consistent, repeatable connections across thousands of thermal cycles—a requirement for reliability in both street and race environments.

This adapter is ideal for builders transitioning between different AN hose sizes during fuel system rerouting or for mechanics consolidating ports on manifolds and block adapters. Installation is straightforward: hand-tighten the female end onto your 16 AN port, then crimp or clamp your 12 AN hose onto the barbed outlet. Compact dimensions (3.15 x 1.9 x 4 inches) allow placement in tight engine bays without fouling ignition or suspension components. Use with PTFE-lined hose and stainless steel clamps for maximum durability, particularly in high-vibration or high-temperature zones.
