Repair of Double Balloon Nozzles

Tried a Beth Tyler Silicone 750cc one year long ,.On a daily use . But it happened one day it was pierced. Can anyone tell me if it s repairable and with what material? .

You can TRY repairing it by cleaning the surface very well with soap and water, then solvents like acetone to make sure all oils and dirt is removed, allowing it to dry overnight and then using GE silicone seal to repair the hole.

I have tried to repair three of these which developed pinholes after a lot of use (usually the just pop and they're toast), but the repair doesn't last at all.

Bite the bullet and get a new one.
