Has my medical Oxygen cylinder been validly hydrostatic pressure tested?2019-04-14T19:57:54+02:00

The date of the hydrostatic pressure test should be engraved in the shoulder of the cylinder. If you cannot find any engravement on the cylinder, the cylinder needs to be hydrostatic pressure tested before it can be filled. If you do not understand the engravement on your cylinder, you can send a picture to our staff.
