Bad News: If you buy the knock- off square tanks, the time will come when you have an issue with a gasket on the top manway. This is normal. The gaskets that are just a phone call to Nikki away don't fit the imposter.
A customer who purchased CMC, Inc. gaskets discovered that they fit the U.S. made tanks only. And the retailer of the imposter tanks was no help on finding a correct gasket.
One solution is to buy the American neck from Custom Metalcraft and weld on the correct dimension top manway assembly and neck.
All of the sudden, that cheap tank without a working gasket got expensive, huh?
Sorry if this happens to you. Please remember these things when you are shopping for wine tanks.
And BUY AMERICAN!
