Parts Desk Insights

Best Use Case: Use for marine wiring connections where you want a sealed crimp termination with shrink tubing and an adhesive-lined heat-shrink seal to help resist vibration and moisture exposure.

Common Issues: If the adhesive-lined tubing doesn’t fully seal, it’s often due to under-heating or misalignment during crimping. Also double-check you’re using the correct tab size (.250 / 6.4 mm) so the disconnect mates securely.
