12AN Swivel Hose Ends Blue STR

The 12AN Swivel Hose Ends Blue STR from REDHORSE PERFORMANCE is a precision-engineered fitting designed for high-flow fuel systems, coolant lines, and custom automotive plumbing applications. Built for enthusiasts and professional mechanics who demand reliability in performance engine builds, this straight swivel hose end accommodates 12 AN (AN12) hose with a 12 AN female port connection. Whether you're upgrading a fuel rail, installing a custom turbo cooling loop, or fabricating a nitrous system, this fitting provides the secure, leak-free connection that separates a quality build from a shop-floor disaster.

Machined from aluminum and finished in blue anodize with accent red detailing, the 12AN swivel design allows hose orientation flexibility without torquing the line itself—a critical feature when space is tight or hose runs must navigate engine bay obstacles. The swivel mechanism reduces stress on hose barbs and fittings during thermal cycling, extending system longevity on boosted or high-heat applications. AN sizing ensures flow capacity matches professional fuel injection and cooling standards; 12 AN hose handles substantial GPM without restriction, making it the go-to choice for naturally aspirated and forced-induction platforms alike.

This straight configuration works best in applications where hose enters the fitting head-on, typical of fuel pump discharge lines, intercooler outlet ports, or power steering return plumbing. The compact footprint—measuring 2.8 x 1.35 x 3.75 inches and weighing just 0.22 lbs—fits snugly in modern and classic engine bays without requiring significant bracket rework. Compatible with any system using 12 AN hose and female 12 AN ports, this fitting pairs seamlessly with Aeromotive, Holley, Edelbrock, and OEM fuel system components, making it essential inventory for any serious performance shop or home garage undertaking a fuel system upgrade or custom cooling project.
