Parts Desk Insights
Best Use Case: Ideal when you want a crimp connection that also includes adhesive-lined heat shrink tubing—commonly used to reduce the risk of moisture intrusion and to add strain/vibration relief after crimping and heat-shrinking.
Common Issues: To get the best seal, ensure the wire is properly stripped to the terminal’s intended crimp length and that the terminal is fully crimped before applying heat. Avoid overheating—apply heat evenly so the adhesive-lined sleeve flows and bonds around the wire insulation and terminal area.
