Hose Fitting #6 Straight PTFE Black

The Hose Fitting #6 Straight PTFE Black is a premium AN-rated hose end connector engineered for high-performance fuel, coolant, and brake line systems in serious street and race applications. Built by FRAGOLA—a trusted name in precision hydraulic fittings—this straight connector eliminates the complexity and potential failure points of traditional threaded adapters. Whether you're upgrading a fuel injection system, plumbing a custom cooling loop, or fabricating a race-ready brake circuit, this fitting delivers the reliability that separates professional builds from amateur work.

The fitting features a 6 AN connection on both ends—6 AN hose to 6 AN female—with a straight geometry that minimizes turbulence and pressure loss in high-flow applications. The aluminum body is anodized in black for corrosion resistance and a clean, professional appearance under the hood. PTFE (polytetrafluoroethylene) hose compatibility ensures compatibility with modern synthetic fluids and extreme temperature swings, critical for turbo cars, LS swaps, and high-horsepower fuel systems operating at sustained boost. The compact design (4.05 inches in length) fits tight engine bays and complex routing scenarios where bulkier fittings create fitment headaches.

This fitting suits custom fabricators, engine builders, and DIY enthusiasts upgrading OEM fuel, coolant, or hydraulic lines to AN-rated systems for superior durability and leak-free performance. Installation requires matching PTFE hose with 6 AN barbed or crimped ends; the female port accepts standard 6 AN male connectors with industry-standard sealing. At just 0.05 lbs, it adds negligible weight while providing the flow capacity and pressure rating needed for turbocharged and naturally aspirated builds alike. Use this fitting as a single component or as part of a complete custom line set for maximum system reliability and aesthetics.
