Cifitcoo AN Hose Assembly Tool 4-16AN with 6 Dies — CNC 6061-T6 Aluminium, Adjustable Clamp

The CIFITCOO 4-16AN fitting installation tool is a complete AN hose assembly kit that seats -4AN through -16AN fittings quickly and securely on CPE fuel lines without extra adapters.

Designed for technicians and DIY mechanics who assemble fuel, oil, or transmission lines, this compact kit replaces fiddly wrenches and guessing with a single adjustable tool and six precision dies. CNC-machined from 6061-T6 aluminum, it clamps standard socket nuts with two set screws so fittings center and compress evenly for a leak-resistant install. The kit covers the common AN sizes used in automotive, marine, and motorsport applications and arrives ready to use—no extra parts required.

How does CIFITCOO speed up AN hose assembly?

This tool simplifies the alignment and seating process, letting you finish a fitting install in about a minute. The holding system removes the need to hold fittings by hand or use multiple wrenches, reducing slippage and rework.

• Two set screws center and clamp the socket nut for steady installs.
• Dedicated dies for -4AN, -6AN, -8AN, -10AN, -12AN, -16AN eliminate die swapping improvisation.
• CNC 6061 construction resists flex so torque goes to the fitting, not the tool.
• Works with common CPE fuel line hose types—quick seating saves shop time.

Will this kit fit different brands and AN nut styles?

The adjustable clamping system accepts standard AN-style socket nuts from most manufacturers, making the tool broadly compatible across brands. It’s not brand-specific, but it’s engineered specifically for AN fittings used on CPE hose types, so verify hose compatibility before use.

• Adjustable two-screw clamp centers various socket nut diameters.
• Standard AN dies accommodate common fitting shapes and sizes.
• Not for non-AN specialty fittings—check hose and fitting type first.

What materials and build quality can I expect?

CIFITCOO builds the housing from 6061-T6 aluminum using CNC machining for consistent tolerances and long life. The robust design stands up to repeated torqueing and shop use without bending.

• 6061-T6 aluminum resists fatigue and corrosion in workshop environments.
• Precision dies ensure repeatable seating and reduce leak risk.
• Compact footprint fits bench spaces and toolboxes for mobile work.

How do I use the tool safely without damaging fittings?

Install the correct die for your AN size, place the socket nut in the clamp, center with the set screws, and drive the fitting home with steady torque—no hammering. Follow hose and fitting manufacturer instructions for final torque and assembly steps to avoid over-compression.

• Select the matching die for the AN size before clamping.
• Tighten the two set screws until the socket nut sits square and secure.
• Apply steady, even torque while watching alignment; stop at recommended torque values.
• Inspect the assembled connection for proper seating and no visible gaps.

Who is this for: The CIFITCOO 4-16AN fitting installation tool is aimed at performance car builders, marine technicians, motorsport crews, and weekend mechanics who assemble AN-style hose ends and want a faster, repeatable way to seat fittings. If you routinely work with CPE fuel line or similar AN-compatible hoses and value durable, portable shop tools that reduce assembly time and handling errors, this kit is a practical addition to your toolbox. Note: confirm hose compatibility before purchase—this tool is designed for AN fittings on compatible CPE-type hoses.
