3M 7000057774 Vinyl Mastic Pad 125 Mil 6.5x4.5 in

Product Description

The 3M 7000057774 is a vinyl mastic pad designed for electrical insulation and void-filling applications in low-voltage and medium-voltage cable and splice work. Each pad measures 6.5 inches by 4.5 inches with a thickness of 125 mil, providing a conformable, moisture-resistant barrier that seals irregular surfaces and protects connections from environmental exposure. Electricians and cable splicers use this pad to wrap splices, connectors, and terminations where a pliable, non-hardening insulating material is required. The vinyl mastic construction conforms to irregular shapes without adhesives, maintaining a tight seal over time.

This pad is suited for residential, commercial, and industrial electrical installations where splice protection and insulation integrity are critical. Typical applications include cable splices, connector bundles, and irregular joint surfaces in conduit or direct-burial wiring systems. Each case contains 50 pads, making it practical for contractors stocking service vehicles or supply rooms for ongoing splice work.

Key Features

• 125 mil thickness for substantial insulation and void-filling performance
• Dimensions of 6.5 inches by 4.5 inches suit standard splice and connector wrap applications
• Vinyl mastic construction conforms to irregular surfaces without hardening
• Moisture-resistant material protects splices from environmental exposure
• 50 pads per case for efficient jobsite and fleet stocking

Compatibility

Designed as an OEM-style insulating pad for use in electrical splice and termination applications where a conformable vinyl mastic material is specified.

Installation Notes

Installation is typically performed by licensed electricians in accordance with NEC guidelines for splice insulation and protection. De-energize and lock out the circuit before working on any splice or termination. Wrap the pad snugly around the connection, overlapping edges as needed to eliminate voids. No tools are required for application, but ensure the mating surfaces are clean and dry before wrapping.
