Self fusing tape is a type of self-adhesive tape that can be used for emergency or temporary repairs to electrical wires, plumbing and hoses.

The design and manufacturing of fire-resistant electrical tape are subject to rigorous testing to meet specific safety standards. When choosing electrical tape for a project, it is crucial to ensure that it is certified by relevant regulatory bodies, such as Underwriters Laboratories (UL) or the International Electrotechnical Commission (IEC). These certifications indicate that the tape has been tested for its fire-resistant properties, assuring users that they are making a safe choice.

Repair Needs: Assess the nature and extent of your repair requirements. Each tape is best suited for different types of repairs.

In addition to being built differently than other tapes, most electrical tapes used by professionals are UL Listed, which means that they have been vigorously tested for performance when exposed to environmental elements, such as cold temperature, moisture, and sunlight. UL Listed electrical tapes are also tested for physical properties, including backing strength, elongation, and adhesive strength and must meet a high standard in order to qualify for the listing. UL Listings exist for many other types of tape – such as foil and film HVAC tapes – but each listing revolves around the specific type of tape in question. So, while your foil tape may meet UL Listing requirements for sealing rigid ducts in HVAC applications, it would not meet the code if used in an electrical application.
