1318-2 Yellow Electrical Tape

This 3M insulating tape uses a polyester film backing with an acrylic adhesive. It measures .25 inches wide and extends 72 yards per roll. The 2 mil thickness provides abrasion resistance for wire insulation tasks. Supplied as a continuous single-sided roll in yellow.

General purpose wire insulation

Suitable for electricians and technicians insulating low-voltage building wire where abrasion resistance matters. Not intended for buyers who need a voltage-rated tape for high-voltage applications. Users requiring a specific minimum temperature rating should look elsewhere. The product has no voltage rating stated by the manufacturer.

265 Degrees F maximum temperature

The tape withstands continuous operating temperatures up to 265 Degrees F. This single thermal limit determines suitability for high-heat environments. No minimum performance temperature is rated by 3M. Verify this maximum against your application requirements before purchase.

Questions about this item

What width and length of 1318-2 tape do I need to cover a 216 ft run?

The roll is .25 in wide and 72 yd long, which equals 216 ft, so one roll covers the full distance.

Will the 2 mil polyester film hold up next to older cloth-insulated wiring rated below 265 Degrees F?

Yes, the acrylic adhesive and polyester backing are rated to 265 Degrees F, well above typical cloth insulation limits.

How can I verify the tape is performing correctly after wrapping a splice?

Check that the yellow polyester film lies flat with no wrinkles, the acrylic adhesive bonds firmly, and the splice remains secure at operating temperatures up to 265 Degrees F.
