Hose Fitting #16 45 Deg Push Lock Black

The Hose Fitting #16 45 Deg Push Lock Black (model 204516-BL) is a precision-engineered AN hose adapter designed for high-performance fuel, oil, and coolant systems in race and modified vehicles. Built by Fragola, a trusted name in motorsport plumbing, this 45-degree fitting serves as a critical junction point in custom fuel systems, turbo upgrades, and engine bay modifications where reliable connections under pressure are non-negotiable. Whether you're assembling a fuel return line in a carbureted engine build, routing coolant in a supercharged application, or designing a complete custom fuel system, this adapter provides the secure, leak-free connection professional mechanics and enthusiasts demand.

This fitting features a 16 AN hose barb inlet matched to a 16 AN female port outlet, allowing seamless integration into systems with consistent AN sizing. The 45-degree push-lock design eliminates the need for clamps or secondary retention on compatible push-lock hose, creating a streamlined installation that saves time and reduces potential leak points common in traditional barbed fittings. Constructed from aerospace-grade aluminum with black anodized finish, the adapter resists corrosion from fuel additives, coolant chemistry, and engine bay heat while maintaining a professional appearance. The anodized surface also provides electrical isolation, a critical feature in fuel systems where static buildup must be controlled. Weighing just 0.34 pounds, it imposes negligible weight penalty while delivering the pressure ratings and flow characteristics required in turbocharged, supercharged, and high-horsepower applications.

Mechanics upgrading fuel systems for LS engine swaps, carbureted restorations, or forced-induction builds will find this 16 AN fitting essential for custom fuel rails, return lines, and surge tank plumbing. The 45-degree geometry allows flexible routing in confined engine bays where straight fittings create clearance conflicts. Installation requires push-lock rated hose (typically -16 AN size) and works seamlessly with other Fragola 8000 Series components to create a complete, matched fuel system architecture. Compatibility extends across port sizes: confirm your fuel line and manifold outlet are both 16 AN female before purchase. This fitting is manufactured to strict tolerances and tested for reliability at pressures exceeding typical street and racing applications, making it a safe choice for builds ranging from mild to extreme.
