1. Product Overview
The iGeelee CT-300A is a hydraulic copper tube expander tool kit designed for efficient and precise swaging and expanding of copper tubing. Made from lightweight aluminum alloy, this tool features a free-floating and self-centering expander mechanism, along with a comfortable long handle grip, to reduce the force needed during operation. It is ideal for various plumbing, HVAC, and refrigeration applications, especially in restricted spaces.
2. Package Contents
The iGeelee CT-300A kit typically includes the following items:
- 1 x Hydraulic Tube Expander (main tool)
- 1 x Tube Cutter
- 1 x Deburring tool
- 7 x Expander Heads (sizes: 3/8", 1/2", 5/8", 3/4", 7/8", 1", 1-1/8")
- 1 pair of gloves
- 1 x Carrying Box
3. Setup Instructions
Before operating the hydraulic tube expander, ensure all components are present and in good condition. Follow these steps for proper setup:
-
Prepare the Copper Tubing
Use soft copper tubing. If using hard copper tubing, heat (anneal) the section to be expanded to make it pliable. This prevents cracking during expansion.
Figure 3: Annealing hard copper tubing. -
Deburr the Tubing
Completely de-burr the inner walls of the tubing using the provided deburring tool. Ensure the tube end is clean and smooth. This is crucial for a proper fit and to prevent damage to the expander head.

Apply Lubricant
Apply a suitable lubricant (preferably grease) to the cone of the expander head before each use. This reduces friction and ensures smooth expansion.

Attach Adapter and Expander Head
Screw the adapter onto the shaft of the hydraulic pump all the way. Then, screw the selected expander head (matching the tubing size) onto the adapter.

4. Operating Instructions
Once the tool is set up and the tubing prepared, proceed with the expansion process:
-
Position the Tubing
Place the prepared copper tubing onto the expander head. Ensure that the expander head travels into the tube FREELY. WARNING: Do not force or twist the tube while placing it on the expander head, as this can damage the tubing or the tool.

Expand the Tubing
Tighten the relief valve knob on the tool. Then, repeatedly operate the active handle (pump handle) until the tubing is expanded to the desired size and the pump handle becomes firm, indicating full expansion.

Release the Tubing
Loosen the relief valve knob to release the pressure and remove the finished expanded tubing. If the tube does not release easily due to configuration or burrs, unscrew the adapter and die head (together) from the pump body to carefully remove the tubing.

5. Maintenance
Proper maintenance ensures the longevity and optimal performance of your iGeelee CT-300A tool kit:
- Cleaning: After each use, clean the expander heads and the main tool to remove any copper shavings or lubricant residue.
- Lubrication: Regularly apply grease or a suitable lubricant to the moving parts of the hydraulic pump and the expander head cone to ensure smooth operation and prevent wear.
- Storage: Store the tool kit in its original carrying box in a dry, clean environment to protect it from dust and moisture.
- Inspection: Periodically inspect the tool for any signs of wear, damage, or loose components. Replace worn parts as necessary.
6. Troubleshooting
Here are some common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Tubing not expanding properly | Hard copper tubing not annealed; insufficient lubrication; incorrect expander head size; relief valve not tightened. | Anneal hard tubing; apply lubricant to cone; ensure correct head size; tighten relief valve knob fully. |
| Tubing stuck on expander head | Tubing forced onto head; burrs on tubing; insufficient lubrication. | Ensure tubing slides freely; deburr thoroughly; apply lubricant. If stuck, unscrew adapter and head together. |
| Pump handle feels loose or no pressure | Relief valve not tightened; air in hydraulic system. | Tighten relief valve. If issue persists, consult a professional for hydraulic system bleeding. |

8. User Tips
- Smooth Operation: Always ensure the tubing slides freely onto the expander head. Forcing it can lead to damage or a stuck tube.
- Lubrication is Key: Don't skip applying lubricant to the expander cone. This significantly eases the expansion process and prolongs tool life.
- Clean Edges: Thorough deburring of the tube ends is essential for a clean, professional expansion and a secure connection.
- Annealing for Hard Tubes: If working with hard copper, annealing the section to be expanded will prevent cracking and make the job much easier.
