I'm building a mash tun on a coleman xtreme 70qt cooler. Most of the directions call for a stainless steel washer on the inside in order for a tight seal. It is widely known that the 1/2" nipple will not fit through the SS washers (though the zinc ones will fit).
I tried to get around this by using the cooler's "washer" on the inside and doing more zinc washers on the outside, but I'm getting a slight leak.
Also have a rubber washer from Lowe's, but I'm not sure that is food grade.
I don't have the tools to expand the SS washer and none of the local stores will do it for me. Is there any food safe alternative I can use to improve the seal on the inside of the cooler?
