Parts Desk Insights
Best Use Case: Use for crimping an 8 AWG marine electrical connection where you want an insulated, sealed termination that’s less vulnerable to moisture intrusion and vibration-related loosening.
Common Issues: Common install issues are improper crimping and incomplete heat shrink—make sure the wire strands are fully captured by the barrel during crimping and that the adhesive lining fully flows as the tubing is heated.
