AOOSEDOO PTFE Hose Assembly Tool Kit for 4AN–10AN — Blue, Reamer + Double‑Ended 6AN/8AN Wrench

The AOOSEDOO PTFE Hose Assembly Tool is a compact kit that trims, reforms and separates PTFE fuel hose layers for faster, cleaner 4AN–10AN hose fittings installation.

This kit combines a purpose-built PTFE hose reaming and separation tool with a double-ended AN fitting wrench to streamline building and repairing PTFE-lined fuel or fluid lines. Designed for use with common 4AN, 6AN, 8AN and 10AN assemblies, the tools speed up the prep work—reshaping cuts, splitting the braided jacket from the liner, and providing the correct wrench sizes to snug fittings without marring surfaces. The set is lightweight, easy to carry, and color-coded blue for quick identification in a toolbox or garage.

How does the tool make PTFE hose preparation faster and cleaner?

The reaming and separation tool is engineered to push into the hose end, reform the cut edge into a round opening and quickly split the braided layer from the PTFE liner. That avoids fiddly, slow work with pins or improvised probes and reduces the risk of frayed braid or compressed liners that impede ferrule seating.

• Re-forms incisions into a neat circular opening for smoother ferrule insertion.
• Separates braided jacket from PTFE liner in seconds, saving assembly time.
• Exchangeable plugs cover multiple AN inner diameters for versatile use.

Will this set fit my 6AN or 8AN fittings, and how does the wrench help?

The included double-ended AN wrench has one jaw sized for a 6AN socket nut and the other for an 8AN B-nut, letting you hold or tighten common AN components without slipping. Using the correct wrench reduces marring and provides the proper leverage for secure, leak-resistant torque.

• 6AN socket jaw (approx. 0.79 in) for internal socket nuts.
• 8AN B-nut jaw (approx. 0.9 in) for outer nut tightening.
• Double-ended design eliminates swapping tools during assembly.

How do the exchangeable plugs expand the tool’s usefulness?

The tool’s plug system lets you swap tips to match different AN inner diameters, so one handle supports multiple hose sizes. This reduces the need for several separate tools and makes the kit adaptable when you’re working on mixed fittings or custom runs.

• Interchangeable plugs accommodate 4AN–10AN range when used with appropriate tips.
• Single-handle operation for consistent control and repeatability.
• Recommended for best results with compatible PTFE hoses and fittings.

What practical results should I expect after using this assembly tool?

Expect cleaner ferrule insertion, faster prep times, and fewer alignment or seating issues when installing AN fittings on PTFE hoses. The improved consistency reduces rework and helps create a more reliable mechanical connection between hose, ferrule and fitting.

• Faster assembly cycles compared with hand tools or pins.
• Neater hose ends and easier olive/ferrule seating.
• Less risk of frayed braid or compressed liner that causes leaks.

Who is this for: The AOOSEDOO PTFE Hose Assembly Tool set is aimed at home mechanics, performance builders, motorcycle and race crews, and hobbyists who assemble AN-style PTFE-lined hoses for fuel, oil, or coolant runs. It’s also useful for anyone retrofitting or repairing fluid lines where a clean, consistent hose end and proper torque on AN fittings matter. If you frequently make or service PTFE hose assemblies and want to save time while improving finish quality, this compact blue kit is designed to simplify the job.
