3M 27 Glass Cloth Tape 180 ft
3M 27 Glass Cloth Tape is a white insulating electrical tape with a glass cloth backing and thermosetting rubber adhesive. It is supplied as a continuous single-sided roll measuring 180 ft in length. The tape carries a voltage rating of 600 V and operates between 32 Degrees F and 302 Degrees F. It suits electrical maintenance tasks requiring abrasion-resistant insulation.
Upgrade from standard PVC tape
Standard PVC electrical tape can degrade under sustained heat or mechanical abrasion. The glass cloth backing and thermosetting rubber adhesive on this roll maintain performance up to 302 Degrees F and resist wear in demanding environments. The jump is worth it when insulation must survive elevated temperatures or repeated physical contact without unwrapping.
Check voltage rating and temperature range
Verify that the 600 V rating meets the circuit requirements for the intended application. Confirm the operating environment stays within the 32 Degrees F to 302 Degrees F performance window. Ensure the 1/4 in width and 180 ft roll length match the project scope before ordering.

Questions about this item
What width and length does the 27 series glass cloth tape come in for fitting a harness wrap?
The roll is 1/4 inch wide and 180 feet long, supplied as a continuous single-sided strip.
How do I apply the thermosetting rubber adhesive on the glass cloth backing, and what step is often missed?
Press the tape firmly onto a clean, dry surface at or above 32 °F so the rubber adhesive wets out; skipping the pressure step leaves weak bonds.
When should I replace the tape on a 600 V circuit given its temperature rating?
Replace if the white backing darkens, cracks or the adhesive bleeds after prolonged runs near 302 °F, as insulation integrity drops.
