Parts Desk Insights
Best Use Case: Use for crimping ring terminals onto 16–14 AWG wire, then shrink the adhesive-lined tubing to help seal out moisture and protect the connection in vibration-prone marine electrical systems.
Common Issues: For best results, ensure the correct crimp size for 16–14 AWG, and verify the adhesive-lined portion fully covers the connection after crimping. If the sleeve doesn’t shrink uniformly, re-check heat-shrink alignment and crimp placement.
