Male Adapter Fitting #6 x 1-20 Rochester Blk

The Male Adapter Fitting #6 x 1-20 Rochester Blk is a precision fluid-line connector engineered for custom fuel, coolant, and brake system installations in performance and classic vehicles. As an experienced mechanic, you'll recognize this as an essential component for builders transitioning between different hose thread standards—particularly when adapting modern fuel injection systems or upgrading fuel delivery on carbureted engines. Rochester (#6) to 1-20 NPT conversion fittings are critical when sourcing components from different manufacturers or retrofitting fuel systems that don't use factory-matched thread sizes.

FRAGOLA's black-anodized aluminum construction provides corrosion resistance essential for underhood environments while maintaining a lightweight profile—crucial for minimizing parasitic mass in fuel systems. The #6 male hose barb design accepts standard 3/8-inch braided hose, while the 1-20 NPT male thread integrates seamlessly into female NPT ports found on fuel regulators, carburetors, filters, and block-mounted adapters. The precision machining ensures leak-free performance under pressure cycles, critical when handling fuel at pressures between 4 and 12 PSI on carbureted systems or higher on EFI applications. Weighing just 0.06 lbs and measuring 1.75 x 1.45 x 4.1 inches, this compact fitting minimizes installation complexity in tight engine bays.

Street rodders, classic car restorers, and fuel system modifiers rely on this adapter when building custom fuel lines for Chevy small-blocks, Ford Windsor engines, and other platforms requiring non-standard port configurations. It's particularly valuable when converting carbureted engines to modern electric fuel pump setups or when installing aftermarket fuel pressure regulators that specify NPT connections. Proper installation requires thread-sealant tape or liquid sealant on the 1-20 NPT threads to prevent weeping under operating pressure—standard practice for any fuel system work. This black finish integrates cleanly into custom engine bays where appearance matters alongside reliability.
