Sealing: It was used for sealing joints and seams in high-temperature applications such as on furnaces, boilers, and other industrial equipment where heat resistance was necessary.

Repair: Asbestos tape was also used for repairing damaged insulation on pipes or electrical wiring.

Fireproofing: Due to its heat-resistant properties, asbestos tape was sometimes used for fireproofing purposes.
