Carb Adapter Fitting #6 x 3/4-16 ORB Short

The Carb Adapter Fitting #6 x 3/4-16 ORB Short by FRAGOLA is a precision carburetor inlet adapter engineered for custom fuel system builds and performance engine modifications. This fitting serves as the critical bridge between AN-rated fuel lines and carburetor inlet ports, making it essential for engine swaps, supercharged platforms, and high-flow fuel delivery systems where factory fittings fall short. Built for enthusiasts who demand reliable, leak-free connections under varying fuel pressures and temperatures, this adapter eliminates the guesswork from fuel line routing.

Constructed from aluminum and finished in black anodized coating, the Carb Adapter Fitting features a 6 AN male connection on one end and a 3/4-16 inch male O-ring seal (ORB) port on the carburetor side. The short design minimizes installation complexity in tight engine bays while the O-ring seal technology creates a positive, vibration-resistant connection that won't weep or fail under thermal cycling. FRAGOLA's manufacturing standards ensure dimensional accuracy and material integrity, allowing this fitting to maintain consistent performance across repeated heat cycles and fuel system pressurization—critical factors in forced-induction and carbureted performance applications.

Street rodders, classic car restorers, and engine builders working with vintage or modern carbureted platforms rely on this adapter when upgrading to braided steel fuel lines or AN fuel system components. The fitting's compact footprint works well in confined spaces where longer adapters create packaging conflicts, particularly in small-block engine bays and tight carburetor bowl configurations. Installation is straightforward—thread the 3/4-16 ORB port directly into your carburetor's fuel inlet fitting using appropriate wrenching, then connect your 6 AN fuel line with a standard -6 AN connector. Verify O-ring condition before assembly and apply light thread sealant to prevent fuel seepage in high-vibration environments.
