I am in the process of doing the 10 gallon rubbermaid cooler (to mash tun) conversion, and had a quick question. I would like to use zip ties to secure the SS braid (as opposed to the clamp which are apparently a bad idea). I see that some people use these, but I haven't found a lot of info on them. Are these zip ties safe to use in 170 degree water? Are there food grade zip ties anywhere? Any help is appreciated, thanks!
