4AN Push Lock Hose End Blue 90-Deg

The REDHORSE PERFORMANCE 4AN Push Lock Hose End Blue 90-Degree fitting is a precision hydraulic connector engineered for high-pressure fluid systems in performance engines, racing applications, and custom fluid routing. This 90-degree swivel hose end accommodates 4 AN PTFE hose with a female 4 AN connection, delivering the directional control and leak-free reliability essential in competitive motorsports, drag racing, and street performance builds where fuel, oil, or coolant systems demand precision engineering.

Constructed from aluminum with blue and red anodized finish, this fitting resists corrosion while providing visual identification of fluid line routing—a critical safety feature when multiple high-pressure circuits run in close proximity. The push-lock design ensures quick, secure engagement without requiring tools, while the swivel connection accommodates vibration and thermal expansion common in engine bay environments. The 90-degree angle eliminates hard bends in hose runs, reducing stress concentration points and extending hose service life. Weighing just 0.05 lbs with compact dimensions, integration into tight engine compartments remains straightforward without sacrificing connection integrity.

This fitting suits builders and technicians assembling custom fuel delivery systems, forced-induction cooling circuits, transmission cooler lines, and aftermarket hydraulic installations where AN hose standards are required. REDHORSE Performance fittings are industry-standard components in shops specializing in engine rebuilds, turbo conversions, and high-output vehicle development. Individual unit sold, allowing precise specification matching for mixed-size hose routing configurations.

The 4AN size bridges small and medium-bore applications, commonly paired with single-stage fuel pumps, auxiliary cooler circuits, and compact forced-induction systems. Buyers sourcing 4AN hose fittings for 90-degree terminations, whether as replacement components or complete system builds, will find this blue-anodized option essential for organized, professional-grade fluid routing in any performance platform.
