The band is awesome and really seals just about anything reliable. For me it was a water hose, where the connection was leaking. I did not want to turn off the water and completely replace the hose, because that would have been quite expensive due to the obstruction. I then tried the belt, wrapped several times (for security more than likely would have been necessary) and the hose is, despite the constant water pressure, now 100% leak-proof. No more dripping. The tape is very flexible, up to 6.5x in length. By distending pressure "welded" the band themselves together and seals so reliably. A great idea that always works in Noftfall. I can only recommend the sealing tape.
