Hose Fitting #16 45 Deg Pro-Flow Black

The Hose Fitting #16 45 Deg Pro-Flow Black from FRAGOLA is a precision-engineered hose end connector built for high-performance automotive cooling, fuel, and hydraulic systems. This 45-degree swivel fitting connects 16 AN hose to 16 AN female ports, making it essential for custom engine builds, race car plumbing, and modified cooling setups where hose routing demands angled connections. Whether you're building a street rod, designing a competition cooling loop, or upgrading aftermarket fuel delivery, this fitting eliminates the need for multiple hose bends and reduces restriction points that compromise flow efficiency.

Constructed from lightweight aluminum with black anodized finish, the Hose Fitting #16 45 Deg Pro-Flow Black resists corrosion while maintaining a clean, professional appearance in engine bays. The swivel design allows the hose to rotate freely once connected, simplifying installation in tight spaces and reducing stress on fittings during engine vibration or thermal cycling. FRAGOLA's Pro-Flow series prioritizes internal passage geometry to maximize flow rate while the 45-degree angle accommodates real-world plumbing constraints without kinking hoses or creating turbulent flow patterns that reduce cooling or fuel system efficiency.

Mechanics and fabricators favor this fitting for custom radiator installs, supercharger intercooler piping, and turbo cooling circuits where 90-degree fittings create flow dead zones. The 16 AN sizing handles high-volume applications typical of V8 engines and forced-induction builds. Installation is straightforward—the swivel feature means no wrench marks on hose barbs, and the smooth internal finish prevents debris buildup that could restrict flow or damage water pumps. For anyone upgrading cooling systems, fuel systems, or building custom hose runs, this FRAGOLA fitting delivers reliable angled connection without performance compromise.
