It is important to use it properly: You have to wrap the tape with rapid train on yourself. This creates a reaction that chemically bonds the plastic itself and also through this train exerts a certain pressure for leaks and holes and it seals so. That's the whole secret behind the 'self-fusing'. It makes me also a great impression and a trial basis so treated tube was very well glued. Only with much effort you can then drag or cut off the tough-knit mass apart.
But! Repair tapes have their purpose, small holes can be so good seal, but help in the long run then usually but only one 'right' repair. Anyone who wants to seal his exhaust so will be ridiculed at the latest by the TÜV for. Besides proper welding helps because only the exchange.
If you want to secure pipe transitions or seals thus additionally is but in good hands here and there is also because of the simple packaging of me a full five stars.
