Will A Plastic Check Valve From Say Petco For A 20 Oz Co2 Tank For A 5 Gallon Work?

    Or do I still have to get something more industrial even though it's a small CO2 set up for a small tank? Thanks.

    IMO a check valve is a check valve, I only have air pumps but my check valves from petco are still working perfectly after over a year
