Ancor Adhesive Lined Heat Shrink Tubing (ALT) - 1" x 12" - 3-Pack - Black

Ancor Adhesive Lined Heat Shrink Tubing (ALT) in 1" x 12" format is an essential solution for automotive wiring harness repair, modification, and weatherproofing. This product is ideal for those working on custom auxiliary circuits or needing to protect exposed connections in various applications, including lifted trucks and marine environments.

The adhesive lining melts inward as heat is applied, creating a permanent, waterproof seal around connectors and splice points without the need for additional sealants or tapes. Made from durable black polyolefin, this tubing resists UV degradation, fuel vapor, and thermal cycling, making it suitable for underhood installations and other challenging environments.

Professional mechanics and custom fabricators rely on this adhesive-lined heat shrink for effective battery terminal insulation and multi-gauge harness repairs. Each tube measures 1 inch in diameter and 12 inches in length, providing ample coverage for multiple connection points, making it a valuable addition to any toolkit.
