Parts Desk Insights
Best Use Case: Use these when you want a crimped ring terminal connection that also gets sealed with adhesive-lined heat shrink for improved resistance to moisture and vibration-related loosening.
Common Issues: Common causes of connection problems include using the wrong wire gauge for the terminal and failing to properly heat-shrink the tubing until the adhesive forms a complete seal. Make sure the ring-terminal fitment matches the 5/16" stud/fastener size before crimping.
