About this item
- End Sleeve Crimper: SN-TG16 ratchet self-adjusting square crimping plier is designed to crimp AWG24 to AWG6 (0.08mm² to 16mm²) wire end ferrules, making fast and solder-free electrical connections.
- Capacity: Optimised crimping range from 0.08-16mm²(AWG24 -6). Crimps uninsulated end terminals, pre-insulated end sleeves and twin-end ferrules.
- Front Entry Crimping Tool: Frontal insertion of wire end ferrules into tool, beneficial with short conductor ends. Very helpful under difficult working conditions in confined spaces for crimping end sleeves.
- Square Crimping: Four lateral crimp profile with four serrated crimp surfaces. Encapsulated crimp eliminates stray wire breakage. Square crimping for optimum contact areas in the clamp connection.
- Advantages: Repetitive, high crimping quality due to integral lock (self-releasing mechanism). Crimping pressure has been set precisely (calibrated) in the factory, re-adjustable. Optimum transmission of force due to toggle lever action for fatigue-reduced operation.

Ferrule and terminal-block fit
Choose the ferrule and crimp profile for the conductor and receiving terminal.
Before ordering
- Check conductor area, ferrule barrel length and whether single or twin ferrules are supported.
- Match the finished crimp profile and dimensions to the terminal manufacturer's requirements.
Can the same range be used for twin ferrules?
Do not assume the single-ferrule capacity applies to twin ferrules. Check the exact tool's stated twin-ferrule capacity.
What should I send for a fit check?
Send the product model, cable or pipe size, connector or fitting part number, and clear photos. Include the intended application so our team can help you identify the appropriate setup.
