The 3 m long and 2.5 cm wide sealing tape is especially suitable for leaks in pipes. There is no tape, therefore, it does not stick well to surfaces but it is "self-fusing" and thus only works when it is wound around a tube overlapping. Thanks to the rubber structure, the belt is also waterproof. For permanent repairs, it is nevertheless not intended, but all for the fast to be treated emergency. Should be part of every household, recommended.
