The oxygen conserver doesn’t attach directly to the steel tank —
it mounts between the cylinder valve and the regulator.
If the Devilbiss cylinder has a CG-A (CGA-870) outlet (standard for medical oxygen in the U.S. & Canada), then:
✔️ The ON-900 conserver will fit as long as the thread pattern matches CGA-870.
Most medical oxygen cylinders from Devilbiss and others use the same CGA-870 connector.
So as long as the Devilbiss tank has the CGA-870 valve, the conserver hardware will physically connect.
