not at all like Teflon tape. Read the amazon description. This is a bit thicker than the teflon tape is and the tape is self fusing. If you stretch it as you wrap it around what you want to seal or repair, it will fuse to itself without any adhesive. Great stuff. I have used it several times for some house repairs. And in a pinch for a slight pipe or hose leak, it can seal the leak.Sounds like Teflon tape that you would use for plumbing fixtures.
