#3 Fem.An Swivel To Male

The EARLS #3 Female AN Swivel to Male 45-degree adapter fitting is an essential component for any serious custom fuel system, brake line, or hydraulic circuit build. Built for high-performance mechanics and engine builders who demand reliability under pressure, this adapter bridges different port configurations while maintaining secure, leak-free connections. Whether you're piecing together a fuel injection system on a carbureted engine swap, rerouting brake lines in a custom chassis, or fine-tuning a cooling circuit, this fitting serves as the precise connector that separates amateur work from professional-grade installations.

Engineered from aluminum and finished with blue anodized coating, the EARLS adapter resists corrosion while remaining lightweight enough for any performance application. The 45-degree angle geometry optimizes hose routing in tight engine bays where straight fittings create unwanted bends or stress points. The female swivel end accepts standard AN hose connections and allows 360-degree rotation to ease installation without twisting the line itself—a critical feature when working with braided stainless steel hose. The male threaded end connects directly to ports, blocks, or other male fittings, eliminating adapter stacking and potential leak points that plague amateur builds.

This size #3 AN adapter (3/16-inch nominal diameter) is the most common choice for fuel supply lines, coolant circuits, and secondary brake systems in street rods, race cars, and restomod projects. Its compact footprint—measuring just 3.05 inches in length and weighing merely 0.02 pounds—makes it ideal for confined spaces where every millimeter counts. Installation requires only a wrench on both ends; the swivel action prevents cross-threading while the anodized finish ensures long-term durability in engine heat and moisture exposure. Professionals and enthusiasts alike specify EARLS fittings for their proven track record in keeping fuel and fluid systems clean, tight, and leak-free for thousands of miles.
