#4 90 Deg Hose End Black

The #4 90 Deg Hose End Black from RUSSELL is a precision-engineered fitting designed for high-performance fuel, oil, and coolant line applications in custom and modified vehicles. Built for automotive enthusiasts who demand reliability in their engine bay plumbing, this 90-degree hose end adapter simplifies complex routing challenges where space constraints or engine compartment layouts require angled connections. Whether you're building a high-horsepower engine bay, fabricating a custom fuel system, or upgrading cooling lines on a heavily modified powerplant, this fitting delivers the durability and flow efficiency your project demands.

Constructed from aluminum and finished in black anodize for corrosion resistance and visual integration with modern engine bays, the #4 90 Deg Hose End Black features full-flow design that eliminates restrictive passages and turbulence at the junction. The 4 AN to 4 AN Female configuration (AN is aerospace notation, denoting nominal hose size in 1/16-inch increments) ensures a secure, leak-free connection using standard AN hose and fittings found throughout performance automotive communities. The 90-degree orientation allows for compact line routing without kinks or excessive bending radius violations that compromise hose integrity and system pressure consistency. Black anodizing provides both aesthetic appeal and protection against oxidation in moisture-prone engine environments.

Mechanics and fabricators working on late-model muscle cars, drag vehicles, and turbocharged street builds rely on RUSSELL fittings for their proven track record and precision tolerances. Installation is straightforward with standard AN wrenches; the female end accepts your 4 AN hose with a reusable or crimped hose barb, while the opposite inlet connects to fuel pumps, carburetors, oil coolers, or cooling system components. Compact dimensions (2.65 x 1.65 x 5.6 inches) and lightweight design (0.08 lbs) minimize weight penalty while maximizing packaging flexibility in tight engine bays. This single fitting works across gasoline, diesel, and alternative fuel systems where quality flow control and durability are non-negotiable.
