IDEAL Electrical™ Wire Armour® Rubber Mastic Tape is a versatile, high-performance solution for insulating and sealing electrical connections. Built with an ethylene propylene rubber (EPR) backing and bonded to a tacky, temperature-stable, electrical-grade mastic, this tape provides outstanding adhesion, flexibility, and durability in demanding environments.

Designed for insulating and moisture sealing splices and terminations up to 2000 volts on solid dielectric cables, it can be wrapped, stretched, or molded around irregular shapes with ease. Its 65 mil thickness delivers reliable insulation build-up, while its self-bonding design ensures a void-free, secure application every time.

I would absolutely recommend these lever connectors and will surely be using them in the future! Those connectors were super easy to work with, didn’t seem flimsy like other brands, and were super easy to install as well as remove
