Parts Desk Insights

Best Use Case: Use this tool when you’re crimping heat shrink terminals on marine or general electrical wiring and want repeatable pressure from a ratcheting mechanism.

Common Issues: For best results, make sure the terminal sits fully in the die window before crimping and that you’re using the correct terminal type for heat shrink insulation (22–10 gauge). If crimps look inconsistent, verify wire gauge and terminal placement against the tool’s die range before continuing.
