120 Degree Hose End Fitt ing; Hose Size: -10 AN

The 120 Degree Hose End Fitting for -10 AN hose size is an essential component for high-performance fuel, coolant, and hydraulic system plumbing in custom automotive builds. Engineered by Vibrant Performance, a trusted name among street rodders, drag racers, and engine builders, this fitting addresses the real-world challenge of routing hoses around engine bay obstacles without kinks or sharp bends that compromise flow. Whether you're upgrading a fuel system on a turbocharged engine, installing custom coolant lines on a LS swap, or fabricating a complete hydraulic clutch setup, precise hose routing determines both reliability and longevity.

Constructed from forged aluminum or ductile iron (depending on application pressure), the 120-degree angle allows hose runs that follow engine compartment geometry while maintaining smooth flow paths that reduce turbulence and pressure loss. The -10 AN designation indicates a nominal 5/8-inch inner diameter hose connection, rated for pressures up to 6,000 PSI on fuel systems and higher on low-pressure coolant circuits. The 120-degree geometry sits between standard 90-degree fittings and straight configurations, giving builders the flexibility to navigate tight spaces around headers, intake manifolds, and firewall-mounted components without requiring multiple adapters or bends that weaken hose integrity.

Performance enthusiasts installing modern EFI fuel systems, custom cooling loops, or aftermarket power steering pumps will find this fitting indispensable for professional-grade plumbing. The compact 3.95 x 1.3 x 4.5-inch footprint fits tight engine bays on classic hot rods, modern muscle cars, and purpose-built race vehicles. Vibrant Performance fittings are manufactured to strict tolerances, ensuring leak-free crimped hose connections that withstand engine vibration, thermal cycling, and boost pressure—critical in turbocharged, supercharged, or naturally aspirated builds where system integrity directly impacts performance and safety.
