Hose Fitting #10 45 Deg Pro-Flow Black

The Hose Fitting #10 45 Deg Pro-Flow Black is a precision 45-degree AN hose adapter engineered for custom fuel, coolant, and hydraulic systems in high-performance automotive builds. Designed for mechanics and enthusiasts who demand reliability in tight engine bays and modified suspension setups, this swivel fitting eliminates alignment stress on hose runs while maintaining a compact footprint. Whether you're running a carbureted hot rod, a turbocharged street car, or a custom cooling loop, this adapter bridges the gap between rigid line work and flexible hose with zero compromise on flow rate or durability.

Constructed from aluminum and finished in hard black anodize, the Hose Fitting #10 45 Deg Pro-Flow Black handles the demands of high-flow applications without weight penalty. The 45-degree angle reduces installation complexity when space is limited—a critical feature in engine compartments packed with headers, intercoolers, or transmission coolers. The swivel design at both ports allows each connection point to rotate independently, preventing hose kinking and fatigue cracking that commonly occurs with fixed-angle fittings. Rated for 10 AN hose on both inlet and outlet sides, this fitting accommodates the same 5/8-inch hose diameter used throughout professional racing and street-performance fuel systems, ensuring seamless integration with existing plumbing.

Mechanics and fabricators rely on Pro-Flow fittings when OEM hose routing won't work in modified applications—engine swaps, EFI conversions, and custom chassis setups all benefit from the directional control this 45-degree adapter provides. The black anodize finish resists corrosion in both wet engine bays and underbody environments, maintaining appearance and integrity over years of hard use. Installation requires standard AN-port tools; the swivel ends accept both push-lock and crimp-style hoses, making retrofit work straightforward. Weighing just 0.16 lbs, this fitting adds negligible mass while eliminating the need for multiple 90-degree elbows that would consume valuable engine bay real estate.
