Mastic tape for electrical insulation
This pack contains ten pre-cut pieces of black vinyl mastic tape measuring three inches by five inches with a six mil thickness. It is intended for electricians and maintenance technicians who need a self-fusing rubber adhesive for splicing and insulating cable up to six hundred volts.
Operating temperature range and voltage rating
The tape performs from fourteen degrees Fahrenheit up to one hundred eighteen point four degrees Fahrenheit, maintaining adhesion and seal across that span. Its rubber-based self-fusing layer bonds without heat and is rated for continuous use at six hundred volts AC.
Pre-cut format and package quantity
Each piece is supplied pre-cut to the stated dimensions, removing the need for trimming on site. The pack quantity of ten pieces allows multiple splices or repairs from a single package.

Questions about this item
How do I apply the self-fusing rubber adhesive correctly on a splice?
Stretch the vinyl-backed tape while wrapping so the rubber adhesive fuses to itself; the step most people skip is maintaining tension through the full overlap.
When should I replace tape that has been on a 600 V circuit?
Replace any length that shows cracking, loss of tack, or carbon tracking; the rubber adhesive does not have a published service interval.
At what temperature does the tape stop performing reliably?
The minimum performance temperature is 14 degrees F and the maximum is 118.4 degrees F; sustained heat beyond that range degrades the self-fusing bond first.
