Sorry, how do I order it in a spare parts house? Because I search on Google and I can't find anything ... I don't know what the aforementioned plastic pipe is like, I've never seen it
It is called "fishing pipe" and comes from a certain length coinciding with the height of the thermos. They come metallic too but will corrode in a short time except that they are made of stainless steel. If you look for them by that name on the network you will find them.
