AN Hose Test & Flushing Kit 6an to 10an

The AN Hose Test & Flushing Kit 6AN to 10AN by FRAGOLA is an essential tool for any serious automotive enthusiast or professional mechanic working with high-performance fuel systems, hydraulic lines, or custom cooling circuits. This kit addresses a critical need in performance builds: verifying line integrity and removing contaminants before installation. Whether you're assembling a turbocharged engine, a custom fuel injection system, or a race-ready hydraulic brake setup, testing and flushing your AN hose assemblies prevents catastrophic failures caused by debris, manufacturing residue, or micro-leaks that would otherwise remain undetected.

This kit covers the full range of commonly used AN port sizes—from 6AN through 10AN—allowing you to pressure-test and flush hoses before they're permanently installed in your system. The modular design accommodates multiple fitting sizes without requiring separate tools or adapters, saving bench space and setup time. By flushing lines with controlled fluid flow, you eliminate factory dust, metal shavings from manufacturing, and oxidation that compromise system cleanliness and accelerate wear on fuel injectors, carburetors, pumps, and valves. Pressure testing confirms that crimped fittings are sealed properly and hose assemblies will withstand peak operating pressures without failure—a non-negotiable checkpoint in fuel system and hydraulic builds where leaks mean performance loss or safety risk.

Professional shops, engine builders, and dedicated hobbyists rely on FRAGOLA's test and flushing kits to validate hose work before final assembly. The compact footprint (5.4 x 2.1 x 8.5 inches) makes it easy to store or transport between bays, while the lightweight design (0.31 lbs) ensures it won't add clutter to your tool collection. Whether you're building a street rod with vintage-style fuel lines, a modern EFI fuel system with strict OEM specifications, or a drag car with redundant cooling circuits, this kit pays for itself by catching defects before they cause expensive downtime or component damage.
