Cifitcoo AN Hose Assembly Tool 4-16AN with 6 Dies — CNC 6061-T6 Aluminum, Universal Fit for CPE Fuel Lines

The CIFITCOO 4-16AN Fitting Installation Tool is a durable, adjustable AN hose assembly kit that seats -4 through -16 AN fittings quickly and accurately for CPE fuel hoses.

If you build or repair performance fuel, oil, or transmission lines, this kit speeds up installations while removing guesswork. CNC-machined from 6061-T6 aluminum, the tool ships with six dedicated dies that match the most common AN sizes (-4AN, -6AN, -8AN, -10AN, -12AN, -16AN). Two set screws provide centering and clamping so fittings sit squarely every time—no more rounded flats, slippage, or repeatedly loosening and retightening.

How does the CIFITCOO tool make AN hose assembly faster?

The tool is designed to let you seat an AN fitting in about a minute without repeated wrenching. Its clamp-and-turn approach holds the socket nut in perfect alignment while you thread and torque the fitting, shrinking installation time and reducing frustration.

• Quick-change dies for each AN size let you switch fittings in seconds.
• Centered clamping prevents cross-threading and reduces rework.
• Ergonomic shape speeds hand turning versus using open wrenches.
• Works on fuel, oil, and transmission CPE hose installations when matched to hose type.

Will this tool fit AN fittings from different brands and styles?

Yes—the adjustable clamping system is brand-agnostic and tolerates minor differences between manufacturers. Two set screws allow you to dial the grip so the tool centers and locks most standard AN socket nuts before assembly.

• Universal fit for standard AN socket nuts across brands.
• Set screws permit fine centering to eliminate play or wobble.
• Included dies precisely match -4 through -16 AN sizing.
• Not intended for non-AN specialty fittings—verify hose type first.

How durable and reliable is the CIFITCOO AN fitting tool?

Constructed from 6061-T6 aluminum and CNC-machined for accuracy, the tool is made to handle typical garage and shop torque without flexing. The robust build keeps die alignment consistent over many uses for dependable, repeatable assemblies.

• 6061-T6 aluminum resists bending under normal assembly torque.
• CNC machining ensures dies and bores remain concentric over time.
• Surface finish minimizes burrs that can mar socket nuts.
• Compact, easy-to-store design fits standard toolboxes.

What should I check before using the CIFITCOO tool?

Confirm your hoses are CPE type and that the fittings are standard AN sizes covered by the kit. The tool is optimized for CPE fuel-line fittings—using it on other hose materials or specialty fittings could produce subpar results or damage components.

• Verify hose material is CPE and fittings are standard AN sizes.
• Match the correct die (-4 to -16) to your fitting before clamping.
• Tighten set screws to center the socket nut, then seat fitting steadily.
• Contact CIFITCOO support for fitment questions or troubleshooting.

Who is this for? This kit suits DIY mechanics, weekend racers, marine installers, and professional technicians who build or repair AN-style fuel, oil, or transmission lines and want quicker, more accurate assemblies. If you regularly work with CPE hoses and -4 through -16 AN fittings, the CIFITCOO tool reduces installation time and helps deliver consistent, leak-free connections when used as directed.
