Cifitcoo AN Hose Assembly Tool 4-16AN with 6 Dies — CNC 6061-T6 Aluminum, CPE Fuel Line Compatible

If you work on fuel, oil, or transmission lines, this CNC-machined tool removes the guesswork from AN fitting installation. Built from 6061-T6 aluminum and supplied with dedicated dies for the six most common AN sizes, the kit centers, clamps, and compresses fittings so you get consistent, leak-free seating without damaged flare nuts or wasted time. It’s designed for CPE-style fuel hose fittings and fits standard AN socket nuts across brands.

How does the CIFITCOO tool make AN fitting installation faster and safer?

The tool replaces awkward wrenches and trial-and-error hand work with a single repeatable process. Two set screws lock the fitting in place so you can apply even pressure and finish assembly in under a minute. That reduces cross-threading, scuffed nuts, and the need to rework connections.

• Two adjustable set screws center and clamp fittings for stable alignment.
• Six dedicated dies match -4AN, -6AN, -8AN, -10AN, -12AN, and -16AN diameters.
• CNC-machined body resists flex under torque for consistent seating.

Which hose and fitting types is this tool compatible with?

It’s specifically tuned for CPE fuel hose style AN fittings and standard AN socket nuts across manufacturers. If your setup uses AN-style socket nuts and common AN flare fittings, the dies will match; confirm hose material and fitting type before use to ensure compatibility.

• Works with standard AN socket nuts from various brands.
• Optimized for CPE fuel line installations—verify hose type first.
• Not intended for non-AN or proprietary fitting designs.

What makes the construction reliable for garage and marine work?

The body is CNC-machined from 6061-T6 aluminum for strength and long life while remaining light enough for handheld use. The precise machining keeps dies aligned under load so fittings seat without wobble or deformation, and the overall design tolerates the repeated torque of shop work.

• 6061-T6 aluminum resists bending and surface damage during use.
• Precision-machined die seats ensure repeatable alignment and pressure.
• Compact footprint fits into crowded engine bays and workbenches.

How do I use the kit for consistent, leak-free results?

Choose the matching die for your AN size, insert the fitting, center it with the set screws, and compress until the nut seats fully. The tool’s mechanics remove lateral play so the nut threads straight onto the hose assembly without cross-threading. Follow torque specifications for final tightening when required.

• Select the correct die for -4AN to -16AN fittings included in the kit.
• Tighten the set screws to center and immobilize the socket nut before seating.
• Compress until the fitting is fully seated; finish to spec with a torque wrench if needed.

Who is this for? The CIFITCOO AN fitting installation tool is aimed at DIY mechanics, professional technicians, boat owners, and motorsport enthusiasts who assemble or service fuel, oil, or transmission lines using AN fittings. If you need faster, more consistent AN assemblies and use CPE-style hoses or standard AN socket nuts, this kit saves time, reduces damage to fittings, and simplifies repeatable installations.
