    Self-Fusing Mastic Electrical Tape

    Image of Product. Front orientation. Electrical Tape. Self-Fusing Mastic Electrical Tape.
    Seal off electrical splices. This tape is thick and molds tightly around connections, filling in gaps and sealing out moisture. Plus, mastic rubber is self-healing—if it gets nicked, it settles to fill the gash and maintain the seal.
    Apply an outer layer of overwrapping tape (sold separately) for a stronger, weather-resistant seal and extra electrical insulation.
    No Facing—Conforms better than tape with a facing, so it seals around irregular shapes. We recommend you wrap this tape with overwrapping tape (sold separately) to protect the seal.
    EPM Rubber Facing—A thin layer of EPM adds excellent electrical insulation without adding bulk, even when wrapped multiple times. However, it’s less abrasion resistant than vinyl facing.
    Vinyl Plastic Facing—Seal your connection in a single step. A vinyl layer is already applied to the mastic for built-in abrasion and weather resistance.
    Putty—Easy to tear and shape by hand, just like clay. Push it into gaps and seams to pad and build coverage.
