#12 30 Degree Hose End

The #12 30 Degree Hose End is a precision-engineered AN fitting designed for high-performance fuel, oil, and coolant line applications in custom and racing vehicle builds. Whether you're fabricating a fuel system for a supercharged engine, upgrading your cooling circuit, or building a motorsport-spec hydraulic line, this AEROQUIP FCM4075 adapter serves as the critical junction between your hose and female swivel receiver. Built for professionals and serious enthusiasts who demand reliable, leak-free connections under extreme pressure and temperature cycles, this fitting eliminates guesswork and delivers the secure, repeatable performance required in competition and street applications.

The 30-degree angled design minimizes sharp bends in your line routing, reducing turbulence and pressure drop while allowing efficient space utilization in tight engine bays—critical when packaging complex fuel injection systems or tight turbo plumbing. This fitting mates a 12 AN hose with a 12 AN female swivel port, allowing independent rotation to prevent cross-threading and hose twist under vibration. The aluminum construction with blue and red anodized finish provides corrosion resistance while maintaining visibility for system identification; the color-coded design is an industry standard that helps technicians quickly verify proper line connections during assembly and troubleshooting. AEROQUIP's reputation for consistency ensures dimensional accuracy and reliable sealing with standard AN rubber or braided hose, eliminating the fitment issues common with lower-grade alternatives.

This 12 AN hose end fitting is essential for anyone fabricating or modifying fuel systems, coolant circuits, or hydraulic lines on turbocharged, supercharged, or naturally aspirated performance platforms. The female swivel design accommodates standard -12 AN hose assemblies and pairs seamlessly with male receiver ports on fuel rails, intake manifolds, radiators, or custom manifolds. Installation requires minimal tools—simply hand-tighten the swivel and apply wrench pressure to the hex body, ensuring proper torque without over-tightening that risks stripping the aluminum. Weighing just 0.33 lbs and measuring 4.5 x 2.5 x 7.2 inches, it fits compact spaces while meeting SAE J518 standards for leak-free performance at pressures common in street and racing applications.
