I am looking for the piece that connects the CO2 tank to the primary regulator. I went to Praxair here locally, and they sold me a piece with the wrong threads. The side that connected to the regulator had regular threads, not left hand. Where can I get one? I looked online on a few sites, but didn't find anything obvious.
On MoreBeer.com, the description for their primary regulator reads as such:
"Comes with a built-in gasket where the regulator connects to the CO2 tank, eliminating the constant replacement of fiber washers."
What does this mean? Is the gasket in the connecting piece? It certainly would be nice to not have to replace the gasket every time I disconnect the tank.
