3M - Super 33+, Vinyl Electrical Tape - Red

3M Vinyl Electrical Tape

Scotch® Super 33+™ Vinyl Electrical Tape is a professional-grade tape that provides electrical insulation for low to high-voltage wires and cables rated up to 600V, with a total thickness of 7 mil (0.178 mm) when applied. This tape is designed with a pressure-sensitive rubber resin adhesive and elastic PVC backing, providing electrical and mechanical protection for a variety of applications. It is known for its versatility, excelling in solid dielectric cable insulation, synthetic cable insulations, jackets, rubber and synthetic splicing compounds, as well as wire and cable harnessing. In critical indoor and outdoor environments, this tape conforms to irregular shapes to create a secure seal on electrical connections and other essential tasks. Its durability allows it to withstand various weather conditions, making it a reliable solution for long-lasting performance. With excellent insulation and adhesion properties, the tape can be used within temperatures from 0 °F to 221 °F (-18 °C to 105 °C), meeting the requirements for flame retardancy

Premium Insulation and Protection

Provides dependable primary electrical insulation for common splice and termination work.

• Primary electrical insulation for wire and cable splices up to 600 V
• Excels in solid dielectric cable insulation, synthetic and rubber cable splicing, cable harnessing, and more
• A durable 7 mil (0.18 mm) tape thickness supports consistent layering for insulation and jacketing
• Offers long-lasting protection for electrical and mechanical operations

Strong Environmental Resistance

Built to withstand outdoor exposure and tough jobsite conditions without sacrificing performance.

• Excellent UV resistance, cold-weather durability, and flame-retardant performance
• High conformability that holds on irregular shapes to create a secure seal
• Enhanced defense on LV/MV/HV joints and splices when used as an overwrap with rubber splicing and mastic tapes
• Ideal for both indoor and outdoor applications

High Adhesion in any Season

Built with a pressure-sensitive rubber-resin adhesive that sticks fast and holds strong across a broad range of conditions.

• Maintains adhesion in cold or humid environments
• Cold-weather application (minimum): 0°F (−18°C)
• Continuous operating temperature (maximum): 221°F (105°C)

Primary Electrical Insulation (Up to 600 V)
Use Scotch® Super 33+™ for low-voltage splicing, terminations, and general insulation. It maintains dielectric strength and a tight seal under stress, vibration, and temperature changes.

Protective Jacketing and Mechanical Overwrap
Apply as an outer jacket layer to guard underlying insulation from abrasion, impact, and moisture. The durable PVC backing and pressure-sensitive adhesive provide long-term resistance to wear and contaminants.

Wrapping Irregular Shapes
High stretch (up to 250%) and excellent elasticity allow the tape to conform smoothly around fittings, joints, and uneven surfaces—creating a uniform, airtight seal without gaps or flagging.

Indoor and Outdoor Splicing and Repair
Engineered for professional performance in all weather conditions—from cold outdoor installs to hot mechanical rooms—Scotch® Super 33+™ adheres securely and stays flexible for durable cable jacket repairs and moisture-resistant splices.
