Need Glycol Leak Sealant That's Food Grade
I have some small leaks at a few threaded connections in my glycol system. I have recommendations for non-food grade type sealants, but can't use them as I make cold liquor via a heat exchanger which poses the risk of cross contamination.
Any recommendations for a good FOOD GRADE sealant?
Currently, I've just taken the fittings apart and wrapped more teflon tape, but it doesn't always work. The paste has been terrible; it seems to promote leaks.
