Hose Fitting #6 Straight Push Lock Black

The Hose Fitting #6 Straight Push Lock Black from FRAGOLA is an essential component for custom fuel, coolant, and hydraulic systems in performance and modified vehicles. Engineered for builders and mechanics who demand reliability in high-flow applications, this straight hose fitting delivers secure, leak-free connections without the complexity of traditional barbed or flared designs. Whether you're fabricating a fuel system for a carbureted engine swap, upgrading to a modern EFI fuel rail, or plumbing custom cooling circuits, this fitting provides the precision required for professional-grade results.

Built from lightweight aluminum with black anodized finish, the Hose Fitting #6 Straight Push Lock Black features FRAGOLA's 8000 Series Push-Lite design that combines ease of installation with proven holding power. The #6 AN (Aircraft National) size accommodates standard 3/8-inch hose diameters, ensuring compatibility with most aftermarket fuel and coolant systems. The straight configuration allows direct, efficient flow paths without elbows or adapters, reducing pressure loss and turbulence—critical factors when tuning carburetor fuel delivery or maximizing circulation in high-temperature cooling loops. The push-lock mechanism securely grips hose without barbed teeth that can fray or damage inner linings, extending hose life and eliminating micro-leaks at critical connection points.

This fitting is ideal for engine builders, hot rod fabricators, and serious DIY mechanics constructing custom fuel systems, intercooler lines, or auxiliary cooling circuits. The 6 AN female port accepts matching male disconnects or adapters, making it a versatile junction point in modular hose assemblies. Installation is straightforward: insert the hose firmly into the barb, and the spring-lock design locks automatically upon seating. For maximum longevity, ensure hose inner diameter matches the #6 specification and apply a light coat of oil to the hose end before insertion. This fitting pairs seamlessly with FRAGOLA's full line of push-lock fittings and adapters for complete system modularity.
