Parts Desk Insights
Best Use Case: Use this adhesive-lined heavy wall BCT when you want the tubing to both insulate and form a sealed barrier over battery cable connections—especially in vibration-prone installations.
Common Issues: For best results, ensure the tube overlaps the connection area and heat evenly so the adhesive activates uniformly. Avoid overheating, which can damage the tubing or insulation—apply heat gradually and keep the heat moving along the length.
