While I love heat shrink crimp connectors I was never fully satisfied with the available crimp tools for professional everyday use. I first developed some custom tools by modifying existing crimp tool frames, testing the pull strength and then worked closely with a German first then a USA manufacturer, who builds crimp tools for AMP, to land on this tool.



The Pro-HST crimper is what I consider a pro-level tool for heat shrink crimp terminals. While this tool is not inexpensive it is made right here in the USA in small lot quantities. The pricing certainly reflects that it is US made and made in small quantities. I generally sell this tool to professionals and occasionally a very discriminating DIY.
