St Alum #6flare/1/4in Pipe

The St Alum #6 Flare/1/4in Pipe fitting from AEROQUIP is a precision hydraulic adapter designed for high-performance fuel, coolant, and brake line systems in modified vehicles and racing applications. This aluminum flare fitting bridges a critical connection point between rigid steel tubing and flexible hose assemblies, ensuring leak-free operation under pressure and vibration. Built for enthusiasts who demand reliability in custom engine builds, turbo installations, and fuel system upgrades, this connector eliminates weak points in your powertrain plumbing.

Constructed from lightweight aluminum alloy, the fitting features a #6 SAE flare end paired with a 1/4-inch pipe thread connection, allowing seamless integration into both metric and imperial system layouts. The flare design creates a metal-to-metal seal that resists bypass and weeping under sustained pressure cycles—critical for turbocharged engines, high-volume fuel systems, and track-duty vehicles where vibration and temperature fluctuations are constant stressors. AEROQUIP's manufacturing standards ensure dimensional consistency and material integrity, minimizing compatibility issues during installation on tight engine bay configurations.

This adapter excels in custom fuel system builds, intercooler plumbing, transmission cooler lines, and hydraulic clutch conversions where space constraints and pressure ratings demand compact, reliable fittings. Mechanics and fabricators routinely specify AEROQUIP connectors for professional restorations, engine swaps, and competition vehicles because the flare-to-pipe transition minimizes turbulence and pressure drop while maintaining thread integrity through multiple assembly cycles. Compatible with standard flare wrenches and available in bulk for complete system builds, this fitting is essential inventory for anyone serious about powertrain modifications.
