Argon/Nitrogen Regulator Adapter, CGA 580 To CGA 320, Tank to CO2 Cylinder

Works like it should

I had problems with 2 adapters that were metal on metal (no o-ring). This worked perfectly. People that give negative ratings because it didn't fit with something else, are blaming the wrong thing. This fit both the CGA 320 and CGA 580 connections. It's also a single piece, so fewer places to have issues. Advice, when you are attaching a CO2 regulator, make sure you have a wrench on the adapter and not just the regulator nut. Also, make sure the regulator can handle the higher pressure or a nitrogen tank.

Did not fit the nitrogen fill kit I bought from amazon.

I tried another adapter without an o-ring to connect a Komos brand co2 regulator with a nitrogen tank, but I could not get a proper seal. However, this one worked great with absolutely no leaks!

Works great
