#6 to 1/2-20 Inverted Flare Steel Fitting

The #6 to 1/2-20 Inverted Flare Steel Fitting by Aeroquip is a precision hydraulic connector designed for high-pressure fuel, oil, and brake line applications in performance vehicles and custom engine builds. This fitting bridges a #6 SAE port to a 1/2-20 threaded connection, making it essential for mechanics upgrading fuel systems, turbo installations, or custom plumbing on modified engines.

Built to handle the demanding requirements of race cars, hot rods, and street machines, this Aeroquip connector ensures leak-free, vibration-resistant connections where inferior fittings would fail. The inverted flare design uses a 37-degree cone seat to create a tight, reliable seal under extreme pressure—critical for fuel systems running high-boost turbos or superchargers. Steel construction provides superior durability and heat resistance compared to aluminum alternatives, preventing thread galling and maintaining integrity through thermal cycling common in high-output applications.

Mechanics and fabricators rely on this fitting when retrofitting fuel rails, installing external fuel pressure regulators, or plumbing custom intake manifold coolant. The #6 SAE port accommodates standard AN fittings and hose barbs found across automotive hydraulic systems. Aeroquip's manufacturing tolerances ensure precise fits that eliminate micro-leaks that plague budget fittings.
