LMSC , indeed, I will leave it for a couple of days, I do not mind losing another as I have a bunch of them & I will report back here.
At the same time, I have shared with Elcor’s support my research for a factory in the US that manufacture a ring in 316 stainless steel with customized sizing & they already do it for heavy duty appliance. so I do not think there will be an issue with them getting rusted or damaged
