#4 90 Degree Hose End

The #4 90 Degree Hose End is a critical hydraulic fitting designed for high-performance automotive fuel and coolant systems where space or engine bay layout demands directional flow changes. Built by AEROQUIP, a trusted name in motorsports and professional automotive plumbing, this 90-degree adapter serves enthusiasts and mechanics upgrading fuel injection systems, custom cooling loops, or turbo applications where hard-line routing isn't practical. Whether you're fabricating a race engine fuel delivery system or modernizing a classic muscle car's cooling circuit, this fitting eliminates the need for expensive custom manifolds by allowing hose runs to turn at precise angles.

Engineered for 4 AN size systems (equivalent to -4 JIC), this hose end features a 90-degree swivel design with a 4 AN female port, accommodating both aluminum and steel construction materials for maximum durability and thermal stability. The red anodized and natural finish resists corrosion while the swivel joint allows final hose orientation adjustment without twisting the hard line, a critical feature when working in tight engine compartments. AEROQUIP's proven AQP/Startlite sealing technology ensures leak-free performance under pressure cycling, making this fitting suitable for fuel pressures up to system specification and coolant temperatures common in modified engines.

Mechanics and fabricators rely on this fitting when building custom fuel rails, intercooler plumbing, or surge tank circuits where 4 AN braided hose must transition direction compactly. Installation pairs seamlessly with -4 AN braided hose and matching male swivel or straight fittings, making it ideal for customers upgrading fuel systems on Mustangs, Camaros, trucks, and vintage hot rods. Weighing just 0.08 pounds with compact dimensions, the #4 90 Degree Hose End integrates cleanly into performance modifications without requiring extensive rework of existing system architecture.
