Specification table for Haisstronica heat shrink wire connector kit

Quick-Change Crimping Jaws let you switch between heat-shrink terminals, wire ferrules, solar connectors, non-insulated terminals, insulated PVC terminals, and open-barrel terminals without changing the complete tool. These hardened-steel replacement dies are made for the Haisstronica 9-inch quick-change jaw crimping tool. Select the jaw by terminal type and wire size before crimping.

How to Choose a Crimping Jaw
  • Identify the terminal construction first: heat-shrink insulated, ferrule, solar, non-insulated closed barrel, insulated PVC, or open barrel.
  • Confirm the conductor size is within the jaw's marked AWG or mm² range.
  • Match the connector to the correctly labeled cavity; do not choose a cavity by color alone when the terminal is not color-coded.
  • Use H4 for non-insulated closed-barrel terminals and H6 for non-insulated open-barrel terminals.
How to Install and Replace the Jaw
  1. Open the Haisstronica 9-inch quick-change crimper fully and make sure no terminal is in the tool.
  2. Release and remove the installed jaw according to the handle's quick-change mechanism.
  3. Inspect the replacement jaw and handle slots for debris or damage.
  4. Align the selected jaw, insert it fully, and confirm it locks firmly with no shaking or slipping.
  5. Close the handle gently to confirm alignment before loading a terminal.
  6. Make a test crimp with the correct terminal and wire size, then inspect the compression and perform a pull test.
Material & Use

The jaws are made from hardened steel with precision grooves and permanent terminal-type and size markings. Use them for repeatable production, repair, automotive, electrical, solar, and workshop crimping only with the specified terminal family and size range. Do not use a jaw on incompatible terminals or cable sizes.

Frequently Asked Questions

Do these quick-change crimping jaws fit every crimper?

No. They are designed for the Haisstronica 9-inch quick-change jaw crimping tool. Compatibility with other crimper frames is not listed.

Does each order include the crimping tool handle?

No. Each product variant contains one selected H1-H6 replacement jaw. The handle is sold separately.

What is the difference between H4 and H6?

H4 is for non-insulated closed-barrel terminals from AWG 22-8. H6 is for non-insulated open-barrel terminals from AWG 20-10.

How do I select the correct jaw cavity?

Match the cavity marking to both the terminal type and the conductor size. After installation, make a test crimp and confirm the compression with a pull test.

Can I change the jaw without tools?

Yes. The compatible Haisstronica 9-inch crimper uses a tool-free quick-change mechanism. Confirm the jaw is fully locked before crimping.
