Plumbers tape?
Not likely, especially if you’re talking about teflon thread tape. Certainly Duct tape might stem the flow, as might bubble gum. You don’t detail the type of pipe, area of the leak, size of the leak area/ issue, or if the water to that location can be turned off. If it can be turned off, do so first. Depending on the pipe type there are methods you might try. I have to believe technology has found ways to create a substance that will effectively block a leak, as well as a diver can WELD under water. The issue might be in the pressure in the line, and the fact that if full, the pushing OUT on any patch will eventually fail the patch. Obviously it might be a moot point if you can isolate the leak. I wonder too of the difficulty and expense for you in just isolating the crak/leak area removing the section and replacing plumbing.
