Parts Desk Insights
Best Use Case: Use these adhesive-lined heat shrink ring terminals when you want a sealed ring termination that resists moisture intrusion and adds strain relief for marine wiring.
Common Issues: For best results, ensure the wire is fully crimped to the terminal and that the heat shrink is heated evenly so the adhesive flows and forms a complete seal. If the connection is not fully sealed, moisture can enter the termination over time.
