Restore dependable insulation and wrap protection on wiring with this universal/spec-match 3M Super 33+ Electrical Tape - 33PLUS. This professional-grade vinyl electrical tape is designed for insulating, wrapping, and protecting compatible electrical connections.

33PLUS is 3M Scotch Super 33+ electrical tape, a universal/spec-match vinyl tape used for wire splices, insulation repair, and protective harness wrapping. It is commonly chosen when better flexibility, temperature performance, and long-term hold are needed than lower-grade electrical tapes provide.

Compatibility: Electrical splices, wire harnesses, insulation repair, and general electrical protection applications where a premium vinyl electrical tape is appropriate.

Please confirm the tape width, length, backing material, adhesive type, and service application before ordering.

Is it time to replace?

• Common Symptoms: Unraveling electrical wraps, exposed splice areas, or brittle old tape that no longer protects wiring reliably.
• Visible/Sensory Cues: Tape lift, cracking, sticky residue, or insulation sections that are no longer fully covered.

Pro Tip: Wrap with slight stretch and overlap so the tape conforms smoothly without bunching at the ends.
