3M 7000026559 Vinyl Mastic Roll 4x10 Ft 600V

Product Description

The 3M 7000026559 is a 90 mil vinyl mastic roll designed for insulating, moisture-sealing, and padding electrical connections rated up to 600 volts. The roll measures 4 inches wide by 10 feet long and is built around a rubber-based, self-fusing insulating compound laminated to a flexible, all-weather grade PVC backing. Rated to 176 degrees F, it holds up under temperature stress and outdoor exposure. Licensed electricians and cable splicing crews use this product when terminating or splicing solid dielectric cable insulation. It conforms easily to irregular surfaces and adheres without additional adhesives.

This vinyl mastic roll is suited for residential, commercial, and industrial electrical applications where moisture ingress and mechanical protection are primary concerns. It performs in pad-mounted transformer connections, cable splices, and termination wrap-ups on solid dielectric cable systems. The all-weather PVC backing resists UV exposure and varying weather conditions, making it appropriate for both indoor and outdoor installations. Each roll is sold as a single unit and is available in cases of 10 rolls.

Key Features

• 90 mil thickness for robust insulation and mechanical protection
• Self-fusing, rubber-based compound conforms to irregular and round surfaces
• Rated to 600 volts for low-voltage cable splicing and termination work
• Temperature rated to 176 degrees F for sustained thermal performance
• All-weather PVC backing resists UV, moisture, abrasion, alkalis, acids, and copper corrosion
• Compatible with solid dielectric cable insulation systems

Compatibility

Compatible with solid dielectric cable insulation. Suitable for connections and splices rated up to 600 volts in all-weather indoor and outdoor environments.

Installation Notes

Installation is typically performed by licensed electricians following NEC guidelines for insulation and splicing at the applicable voltage rating. De-energize and lock out the circuit before applying mastic wrap to any conductor or splice. Stretch the roll slightly during application to activate self-fusing properties and ensure full surface contact. Overlap each wrap layer by at least half the roll width for consistent moisture and insulation coverage.
