3M 7000006032 Mastic Electrical Tape 1 in X 10 Ft 125 Mil

Product Description

The 3M 7000006032 is a mastic-adhesive electrical tape designed for insulating and sealing applications in electrical systems. Measuring 1 inch wide and 10 feet long with a 125 mil thickness, this heavy-body tape provides a conformable, void-filling wrap around irregular surfaces such as splices, connectors, and cable terminations. The mastic adhesive bonds to a wide range of substrates without requiring a primer, making it a dependable choice for field repairs and primary insulation work. Licensed electricians and electrical contractors are the primary installers. It is rated for operating temperatures from 0 degrees F to 194 degrees F.

This tape is suited for low- and medium-voltage electrical insulation and moisture sealing tasks in both residential and commercial settings. Common applications include wrapping cable splices, sealing conduit entries, and insulating irregular geometries where rigid or thin-film tapes cannot conform adequately. Its black color helps identify it as an insulating layer in multi-tape system builds. The 3M series number for this product is 2229.

Key Features

• 125 mil mastic thickness conforms to irregular cable and connector surfaces for void-free coverage
• Operating temperature range of 0 degrees F to 194 degrees F suits a wide range of service environments
• Mastic adhesive bonds without a primer to most clean electrical substrates
• Single-roll, 10-foot length is sized for splice and termination work
• Dual-function use for both insulating and sealing in one tape application

Compatibility

Designed as an OEM-style insulating and sealing tape for use in low- and medium-voltage electrical splice, termination, and conduit-sealing applications where a conformable mastic-adhesive tape is required.

Installation Notes

Installation should be performed by a qualified electrician following applicable NEC requirements. De-energize and lock out the circuit before applying tape to any splice or termination. Clean and dry the substrate before wrapping to ensure proper mastic adhesion. Stretch the tape uniformly during application to achieve full conformance around irregular surfaces and eliminate air voids.
