- Intended Use: Use the tool only for its intended purpose of crimping hydraulic hoses with compatible dies.
3. Product Overview
The LABFENG MK16-3mm Hydraulic Hose Crimping Tool is a robust, handheld device designed for efficient hose assembly. It features a durable steel construction and an ergonomic grip for comfortable operation.
3.1 Main Components
- Crimping Head: The main body where the dies are installed and the crimping action occurs.
- Hydraulic Pump Handle: Used to generate hydraulic pressure for crimping.
- Pressure Release Valve: Allows for controlled release of hydraulic pressure.
- Dies: Interchangeable segments that form the crimp around the hose fitting. The MK16-3mm model is designed for 3mm molds.

3.2 Die System
The tool utilizes magnetic dies for easy installation and removal. The MK16-3mm model is specifically designed for 3mm molds, but the system supports various sizes as shown in the die cavity dimensions.
Figure 2: Mold Cavity Dimensions. This diagram illustrates the different sizes and shapes of crimping dies, including 10mm (1/8"), 14mm (1/4"), 16mm (5/16"), 19mm (3/8"), 23mm (1/2"), 27mm (5/8"), and 30mm (3/4"). It also shows the internal structure of the dies.
4. Setup
Before operating the crimping tool, perform the following setup steps:
- Unpacking and Inspection: Carefully remove the tool from its packaging. Inspect all components for any shipping damage. Report any damage to the supplier immediately.
- Hydraulic Fluid Check: Ensure the hydraulic reservoir is filled with appropriate #46 hydraulic fluid. If not, fill to the recommended level according to the manufacturer's guidelines. Refer to the tool's specific markings for fluid type and capacity.
- Die Selection: Select the correct die set (e.g., 3mm mold) that matches the hose and fitting specifications you intend to crimp. Refer to Figure 2 for die dimensions.
- Die Installation: Open the crimping head and carefully place the selected magnetic dies into their respective slots. Ensure they are seated correctly and securely.
- Familiarization: Operate the pump handle a few times without a hose to familiarize yourself with the tool's action and the pressure release mechanism.
5. Operating Instructions
Follow these steps for safe and effective hose crimping:
- Prepare Hose and Fitting: Cut the hydraulic hose to the desired length and prepare the fitting according to its manufacturer's instructions. Ensure the hose end is clean and free of debris.
- Insert Hose and Fitting: Insert the hose end with the fitting into the crimping head, ensuring it is centered within the dies. The fitting collar should rest evenly against the dies.
- Initiate Crimping: Close the crimping head securely. Begin pumping the hydraulic handle. You will feel resistance as the dies begin to close around the fitting.
- Monitor Crimp: Continue pumping until the desired crimp diameter is achieved. Many crimpers have a built-in gauge or stop mechanism to indicate when the crimp is complete. Refer to your fitting manufacturer's specifications for the correct crimp diameter. This process may require numerous pumps.
- Release Pressure: Once the crimp is complete, slowly open the pressure release valve to retract the dies.
- Remove Crimped Hose: Carefully remove the crimped hose assembly from the tool.
- Inspect Crimp: Visually inspect the crimp for uniformity, proper depth, and any signs of damage or incomplete crimping. A properly crimped fitting should be secure and evenly compressed.
6. Maintenance
Regular maintenance ensures the longevity and reliable performance of your crimping tool:
- Cleaning: After each use, clean the crimping head and dies to remove any dirt, grease, or hose debris. Use a clean cloth and a mild solvent if necessary.
- Lubrication: Periodically apply a light coat of oil to the moving parts of the crimping head and dies to prevent rust and ensure smooth operation.
- Hydraulic Fluid Level: Regularly check the hydraulic fluid level. Top up with #46 hydraulic fluid as needed. Refer to the tool's markings for the correct fluid type and filling procedure.
- Storage: Store the tool and dies in a clean, dry environment, protected from dust and moisture. The integrated die storage drawer (Figure 1) is ideal for keeping dies organized and protected.
- Inspection: Periodically inspect the tool for any signs of wear, loose fasteners, or damage. Address any issues promptly.
7. Troubleshooting
Refer to the following table for common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Tool not crimping / Pump not building pressure | Low hydraulic fluid level Air in the hydraulic system Faulty pump mechanism Pressure release valve open | Check and refill hydraulic fluid Bleed air from the system (refer to specific tool instructions) Contact customer support for repair Ensure pressure release valve is fully closed |
| Hydraulic fluid leakage | Loose connections Damaged seals or O-rings Cracked housing | Tighten all connections Replace damaged seals/O-rings Contact customer support for repair |
| Inconsistent or poor crimps | Incorrect die size Improper hose/fitting preparation Insufficient pumping pressure Worn dies | Verify correct die selection for hose/fitting Ensure hose and fitting are properly prepared and seated Pump until specified crimp diameter is reached Inspect and replace worn dies |
| Dies not retracting | Pressure release valve not fully opened Obstruction in crimping head | Ensure pressure release valve is fully opened Inspect crimping head for debris and clear any obstructions |
