Electrical tape 3M SUPER33+-19X33

The 3M SUPER33+-19X33 electrical tape is a multi-purpose insulating tape constructed from a durable rubber-based backing with a pressure-sensitive adhesive. Supplied in black with a roll length of 33 m and a width of 19 mm, the tape has a thickness of 0.18 mm and is designed to provide reliable electrical insulation, moisture resistance and mechanical protection for wiring and cable joints in a variety of environments.

Advantages

This electrical tape combines strong adhesion with long-term flexibility to maintain a secure, conforming wrap around irregular shapes and connectors. Its rubber-based composition offers good resistance to moisture and aging while preserving dielectric properties required for insulating electrical conductors. The tape’s moderate thickness and elastic nature help absorb mechanical stress and provide abrasion protection without significantly increasing bundle size.

Suitable for

• Insulating and bundling electrical wires and cables
• Sealing and protecting cable splices and terminations
• Temporary repairs and color-coding of wiring
• Indoor and outdoor electrical maintenance where moisture resistance is needed

Key specifications

• Material: rubber-based backing with pressure-sensitive adhesive
• Color: black
• Width: 19 mm
• Length per roll: 33 m
• Thickness: 0.18 mm
• Pack quantity: 48 pieces per pack

How to use

Prepare the conductors or cable ends by cleaning and drying the surfaces to ensure good adhesion. Start wrapping the tape at least one full turn past the repair or splice, applying firm, even tension and slightly stretching the tape as you wrap to form overlapping layers. Continue until the area is fully covered and extend the wrap beyond the splice to provide a secure seal. For multiple layers, ensure each turn overlaps the previous one by about half the tape width to achieve consistent insulation thickness.

Usage recommendations

Store the tape in a cool, dry place away from direct sunlight and extreme temperatures. For permanent installations, evaluate application requirements and local electrical standards to confirm suitability. When working on live circuits, follow appropriate safety procedures and disconnect power where possible before applying the tape.
