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.

Glass Sealing Rope

Press this pliable rope into place to hold glass in window frames and seal leaks. It’s also known as glazing compound. The rope is non-sagging, so it won't drip from vertical and overhead surfaces. It’s good for use between dissimilar materials and in environments with wide temperature fluctuation. Remove the peel-off liner to install.
