Storing cylinders

Hello all, I found some older information and wanted to see if there is anything new or current on this topic. Is there a best practice for storing air cylinders, both short-term and long-term, with or without air in them? I have air in them short-term just because I practice almost daily, but I'm wondering about long-term storage with air in them. Also, what would be considered short-term vs. long-term time periods?


I'm using a Pardini K12J.

Pre charged pistol air cylinders should not be stored on the pistol or you can use a seperator/spacer to disconnect the tank from the pistol.
This will allow the pressure regulator to be depressurised, giving a longer life to the spring pile of the regulator.
As the tanks are storing static pressure, fatigue should not be a issue but for long term storage to keep seals in place
maybe store at pistol minimum pressure i.e. about 80 bar.
Store in a cool dry place.

For long term storage, leave the cylinder of the pistol, for the reason above.

As for the cylinders, I don't think it matters if they have pressure or not. The seals will degrade over time, regardless of pressure, and when they let go, the cylinder will leak. It's sort of a built in fail safe, so that it leaks before fatigue causes them to crack.

Hope this helps
