## Description

Tank to Regulator Adaptor is used to convert a CGA-580 Nitrogen/Argon tank to a CGA-320 Carbon Dioxide (CO2) regulator.

Review: Works - Works like it should
Review: This Solved My Need - 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.
