Hose Fitting #20 Straight Black

The FRAGOLA Hose Fitting #20 Straight Black (Part #100120-BL) is a precision aluminum hose end connector engineered for high-pressure fluid systems in motorsports, aerospace, and performance automotive applications. This straight-configuration fitting connects a 20 AN hose directly to a 20 AN female receptacle, providing a leak-free seal without the space requirements of angled alternatives. The black anodized finish offers both corrosion resistance and a professional appearance in engine bays and fluid line assemblies.

FRAGOLA's 3000 Series hose fittings are manufactured to handle pressures commonly encountered in fuel injection, transmission cooling, and brake line systems. The aluminum construction keeps weight minimal while maintaining structural integrity under thermal cycling—a critical consideration in high-performance engines where aluminum-to-aluminum connections resist galvanic corrosion better than mixed-metal assemblies. The 20 AN designation refers to a nominal hose diameter of 1.25 inches, appropriate for mid-to-high-flow applications requiring substantial volume capacity without excessive pressure drop.

This straight hose fitting serves builders who prioritize direct, in-line connections where space allows. Typical installations include coolant bypass lines, fuel return lines in carbureted engines, transmission cooler circuits, and custom hydraulic systems. The black anodized finish integrates cleanly into modern engine compartments and resists anodic corrosion in salt-air environments. Each fitting is sold individually, allowing precise line customization without surplus hardware inventory.

When selecting hose fittings for pressurized systems, matching the correct AN size, thread type (female vs. male), and orientation (straight vs. angled) to your existing line and receptacle prevents costly leaks and system failures. FRAGOLA's 3000 Series is a recognized standard in the restoration and custom automotive community, trusted for both original equipment replacement and purpose-built applications.

The fitting weighs 0.45 lbs and ships as a single unit, allowing you to purchase only the exact connectors your system requires. Whether you're assembling a fuel system for a vintage restoration, a high-flow cooling upgrade for track duty, or a custom-fabricated hydraulic circuit, this straight connector delivers the reliability expected from FRAGOLA's engineered line of fluid system components.
