180 Degree Hose End Fitt ing; Hose Size: -4 AN

The 180 Degree Hose End Fitting for -4 AN hose from Vibrant Performance is engineered for builders who demand precision in fuel, coolant, and brake line routing. This compact adapter solves a universal challenge in custom engine bays and modified cooling systems: redirecting fluid flow at sharp angles without kinks, leaks, or flow restrictions. Whether you're fabricating a custom fuel system, designing a remote oil cooler setup, or routing brake lines around engine bay obstacles, this 180-degree elbow lets you maintain -4 AN compatibility while executing tight-radius bends that straight fittings simply cannot accommodate.

Vibrant Performance's 180-degree design uses a full-flow internal radius that minimizes turbulence and pressure drop compared to cheaper stamped alternatives. The -4 AN port size (common in street and race applications up to moderate horsepower levels) threads securely into standard -4 hose ends and adapters without requiring additional reducers or adapters. Weighing just 0.06 lbs and measuring approximately 3.3 x 0.8 x 3.6 inches, the fitting is compact enough to fit tight spaces while maintaining structural integrity under pulsating fuel pressure, boost, or coolant circulation. The precision-machined construction ensures a leak-free seal when paired with proper hose crimping and AN-standard assembly techniques.

Mechanics and fabricators building high-performance fuel injection systems, turbo cooling circuits, and custom brake setups rely on this fitting to achieve clean, functional plumbing without dead-leg bypass routes. Installation requires basic hand tools and an understanding of AN fitting torque specifications—typically 15–25 ft-lbs depending on material and thread sealant. Compatible with all standard -4 AN hose assemblies, crimped fittings, and adapter networks, this 180-degree elbow integrates seamlessly into modular fuel and coolant architectures. For street cars, track vehicles, and engine swaps where routing efficiency and reliability matter, this Vibrant Performance fitting delivers straightforward, proven performance.
