Hose Fitting #4 Straight Black

The Hose Fitting #4 Straight Black from FRAGOLA is a precision aluminum hose end connector engineered for high-performance fluid systems in automotive applications. This 4 AN (AN4) straight fitting is essential for builders and mechanics who demand reliable, leak-free connections in fuel, oil, coolant, and brake line routing. Whether you're fabricating a custom fuel system for a modified engine, plumbing high-flow cooling circuits, or restoring a classic car's hydraulic lines, this fitting delivers the durability and consistency that separates professional-grade work from amateur installations.

Constructed from lightweight aluminum and finished in durable black anodizing, the Hose Fitting #4 Straight Black features a straight configuration that eliminates bulky 90-degree elbows in tight engine bays and chassis tunnels. The 3000 Series design accommodates 4 AN hose on one end and 4 AN female threads on the other, ensuring JIC-compliant pressure integrity without adapter stacking. Black anodization provides superior corrosion resistance and a clean appearance under the hood, while aluminum construction keeps system weight minimal—critical for performance vehicles where every pound matters. The compact dimensions (3.1 x 0.95 x 4 inches) allow flexible routing without sacrificing strength or flow capacity.

This fitting benefits race teams, hot rodders, and restoration specialists who require precision plumbing in confined spaces. The straight design is ideal for fuel rails, bypass circuits, and transmission cooler lines where 45 or 90-degree bends would compromise access or create stress points. Installation is straightforward: crimp or attach your AN hose to the barbed inlet and thread the female end directly into your system component. Compatible with any 4 AN hose assembly and standard JIC female ports, it pairs seamlessly with carburetor fuel systems, mechanical fuel injection, turbo oil supply lines, and custom hydraulic circuits. One fitting weighing just 0.04 lbs, it's an economical solution for point-to-point connections that demand professional reliability.
