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.

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.

Thread Sealant Tape

Made of PTFE, this tape has a slippery surface that keeps threads from binding to make parts easy to assemble.

ePTFE with Graphite—ePTFE tape with graphite creates a better seal between threads than plain PTFE tape, which helps prevent fluid and gas leaks. The graphite attaches to the PTFE, so this tape does not emit harmful VOCs.
