I would never attempt that myself without knowing about the tube.. I just am not so sure about how much temp my tubing can handle. I wouldn't try it unless I was sure.
For my strike water and everything on my AG system I use a braided hose that is rated to take boiling water. It's from Goodyear.
If I were you or myself and doing it over again, I'd get some silicone tubing from one of the online HB shops.
Then again it could be that you have hi temp tubing and its fine, hard to tell.
But avoid the risk of plastic and chemical leeching above all else.
Cheers
