Professional-grade vinyl electrical tape

3M Scotch Super 33+ vinyl electrical tape provides reliable insulation for general-purpose electrical work. Each roll delivers 44 ft of 7 mil thick tape with a rubber adhesive that bonds securely to wire and cable. The continuous roll format allows clean, custom-length cuts for every connection. Packaged in a 100-count case for high-volume jobs.

Temperature-rated performance under load

The tape maintains its insulating properties across a wide operating range from 0 degrees F to 221 degrees F. Rubber adhesive resists flagging and unwinding when subjected to sustained heat or mechanical stress. Vinyl backing stretches and conforms to irregular shapes without splitting during long-term service. Rated for 600 V applications in continuous duty.

100-roll bulk packaging constraint

Buyers who need only a few rolls for occasional repairs will find this case quantity excessive. The 100-pack is intended for contractors and maintenance teams with steady consumption. No smaller pack size is offered in this listing. Storage space for a full case should be planned before ordering.

Questions about this item

Does the 7 mil vinyl hold up when the job site hits 221 °F all day?

The tape is rated for continuous use up to 221 °F, so it stays bonded and flexible even in high-heat panels or engine bays.

What tools or surfaces do I need before I start wrapping with this 1-1/2 in roll?

Clean, dry wire or conduit is all that’s required; the rubber adhesive sticks to itself and most electrical insulations without primer.

Can I trust the 600 V rating on the older cloth-insulated cable I’m repairing?

Yes — each roll is tested to 600 V, so it safely re-insulates legacy wiring that originally carried that voltage.
