To be honest I have no clue. I'm guessing stuff like brewery or possibly exterior runs...lemme know if you want any, I dont need to sell in 1 lot. Figured maybe a plumber or something may have a use for them.
LOL, thanks. Glad I'm not only one... Yeah, I really don't "need" any but a couple might be nice. This would be just for standoffs for a bench not used for any fluids, etc...
They are for the food industry mainly. Most residential plumber won’t have a use for them. Commercial plumbers yes. See if there is a dairy plant or other food plant near by and they may purchase them from you. I worked in a dairy and this was all we used.
