Parts Desk Insights
Best Use Case: Use these adhesive-lined heat shrink ring terminals when you want a crimped ring lug connection that’s sealed against moisture and supported against vibration and pull/strain in marine environments.
Common Issues: For best results, ensure the correct ring terminal size matches your wire gauge and your mounting stud/fastener size (3/8"). Proper crimping is important—an under-crimped connection can reduce conductivity and may compromise the sealing performance when the heat shrink is shrunk.
