    Electrical Tape

    Image of Product. Front orientation. Electrical Tape. Electrical Tape.
    Your go-to electrical tape thanks to its excellent insulation. This vinyl tape is used for everything from insulating live wires up to 600V to overwrapping base layers. It’s exceptionally stretchy for a tight wrap around your connection.
    General Purpose—Best for everyday electrical or fastening jobs. This tape is the most conformable option, but provides less protection against wear and damage than thicker alternatives.
    Weather Resistant—Withstands long-term outdoor exposure. Offering a good balance of conformability and protection, this tape won’t degrade from direct sunlight, moisture, and temperature changes.
    Abrasion Resistant—Our thickest vinyl option. This tape holds up against scrapes and constant vibration from operating machinery, but doesn’t stretch as easily or conform as tightly as other tape.

    Insulate hard-to-reach connections. Brush, dab, or spray liquid tape to create a skintight layer that covers and hardens over uneven surfaces and fills small gaps. It can also be used to seal plastic tape.
    Liquid Vinyl Plastic—Great for quick insulation repairs. Thinner than liquid rubber when applied, a single coat dries in five minutes or less. Add additional coats as needed to build up insulation.
    Liquid Rubber—Dries into an elastic coating that creates a thick, flexible seal. When removed, it comes off cleanly and won’t leave residue behind.
    Cannot Be Sold Outside United States—Liquid that cannot be sold outside the United States is restricted by product labeling requirements.

    Ultra-Thin Polyester Electrical Tape

    Image of Product. Front orientation. Electrical Tape. Ultra-Thin Polyester Electrical Tape.
    At 0.0025" thick, this is our thinnest electrical tape, yet it still gives you excellent insulation. It's a great choice for tightly packed electronics where thicker tape would be too bulky. Use it to hold components under light tension.
    Rubber Adhesive—Bonds quickly when applied to a surface. This tape’s tacky grip offers a strong initial hold, but it won’t last as long as tape with acrylic adhesive and leaves behind residue when removed.
    Acrylic Adhesive—Long lasting and solvent resistant. The adhesive won’t degrade when exposed to chemicals, oil, or prolonged UV light. Unlike rubber adhesive, it leaves behind little residue when removed.

    Self-Fusing Mastic Electrical Tape

    With Facing

    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.
    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.

    Reinforced with fiberglass filament, this tape won’t snap under high pressure loads. It’s often used to insulate transformer coils, motor windings, and other electrical parts.
    Rubber Adhesive—Bonds quickly when applied to a surface. This tape’s tacky grip offers a strong initial hold, but it won’t last as long as tape with acrylic adhesive and leaves behind residue when removed.
