    Self-Fusing Rubber Sealing Tape

    Image of Product. Front orientation. Repair and Duct Tape. Self-Fusing, Sealing.
    Bonds to itself for a permanent, watertight seal. This tape has no adhesive, so it won't dry out and crack, which can cause standard tape to fail over time. The rubber backing molds to irregular surfaces and withstands demanding conditions, making this tape a good choice for patching and sealing anything from roofs to pipes.
    Butyl Rubber—Creates an airtight, impermeable seal. It also stretches and conforms better than EPDM rubber tape.
    EPDM Rubber—A good choice for outdoor applications, it withstands sunlight, ozone, and weathering.
    Polyolefin/Rubber—Sticks to most surfaces, including vinyl, fiberglass, PVC, wood, tile, and even damp nonporous surfaces.
    Silicone Rubber—Your best choice to repair pipe, this tape withstands harsh chemicals and the widest temperature range. However, it breaks down when exposed to oil, grease, or fuel.
