Hose Fitting #4 150 Degr

The FRAGOLA Hose Fitting #4 150 Degree (SKU FRG115004) is a critical component for any high-performance fuel, coolant, or hydraulic system requiring reliable, angled connections. Built for automotive enthusiasts and mechanics who demand precision in custom engine builds, racing applications, and comprehensive vehicle modifications, this 4 AN hose fitting solves the real-world challenge of routing lines through tight engine bays without kinks or compression loss. Whether you're assembling a stroker motor, upgrading to a fuel injection system, or fabricating a custom cooling loop, this fitting delivers the secure, leak-free connection that separates amateur builds from professional results.

Constructed from lightweight aluminum and finished in blue and red anodized coating for corrosion resistance and easy identification in complex plumbing layouts, the Hose Fitting #4 150 Degree features a 150-degree bend angle that accommodates space-constrained engine compartments without requiring bulky adapters or secondary elbows. The 4 AN to 4 AN male swivel design ensures smooth hose rotation during installation and eliminates stress on fittings during vibration cycles—critical for longevity in high-RPM applications. The swivel mechanism allows unrestricted hose movement, reducing pressure spikes and connection fatigue that commonly cause leaks in non-swivel alternatives.

Professional mechanics and weekend fabricators alike rely on FRAGOLA fittings for forced induction systems, custom fuel rails, transmission coolers, and intercooler circuits where compact routing and vibration isolation matter most. The compact dimensions (2.9 x 2.1 x 4.95 inches) and minimal 0.08 lb weight make this fitting ideal for weight-conscious builds without compromising structural integrity. Install with standard 4 AN hose and compatible fuel system components; the anodized finish resists ethanol fuel degradation and coolant corrosion, ensuring years of dependable service in demanding underhood environments.
