3M 7100201470 | 33+-3/4X76FT-1 Scotch 76' OAL x 0.750" Width x 7.0 mil Thickness Electrical Tape

Description

3M 7100201470 Scotch Super 33+ vinyl electrical tape is a high-quality insulating tape intended for primary electrical insulation up to 600 volts. This tape, which is 7 mil thick and 33+super-3/4x76 ft in size, provides long-lasting mechanical and moisture protection for splices, harnessing, and cable jacketing in both indoor and outdoor applications. It is conformable down to 0°F (-18°C) and performs continuously up to 221°F (105°C), making it appropriate for a variety of wire types and environments. The PVC backing and pressure-sensitive rubber adhesive are resistant to abrasion, UV, alkalis, and many solvents, allowing the tape to maintain a moisture-tight seal without adding unnecessary bulk. Installers who require consistent, measurable insulation properties and repeatable application performance will find this 3M Scotch Super 33+ Vinyl Electrical Black Tape ideal for routine splicing, bundling, and jacket repairs, including the black color option commonly stocked for service work.

Product Features and Benefits

Primary electrical insulation to 600 V

Rated for use on wires, cable splices, and bus applications up to 600 volts, the tape provides code-friendly primary insulation in compact wraps.

7 mil PVC backing for mechanical protection

The 7 mil backing balances flexibility and tear resistance to protect splices and jacket repairs from abrasion and handling damage.

Wide operating temperature range

3M Scotch Super 33+ Vinyl Electrical Tape is designed for continuous use in temperatures ranging from 0°F to 221°F (-18°C to 105°C); it is suitable for both cold-weather installations and high-temperature environments.

Durable resistance to weather and chemicals

Formulated to resist UV, moisture, alkalis, acids, and many solvents, this tape maintains adhesion and dielectric performance outdoors and in harsh conditions.

Conformability and low bulk wrapping

Elastic PVC construction allows half-lapped wraps that produce a moisture-tight wind while minimizing added diameter on splices and pigtails.
