All cylinders ordered and delivered through the Gasciti service will always have a plastic seal around the valve of the cylinder. This seal is your guarantee that the cylinder has passed a final check in our filling process and is the correct weight and in a safe working condition.
Gasciti does not refund stock that was correctly invoiced and delivered. Should a cylinder have been ordered and subsequently discovered to be the wrong size, Gasciti will exchange the cylinders for the correct size as long as the original cylinder still has its plastic seal around the valve intact. Please feel free to contact us personally in regards to your individual situation should you wish to discuss refunds or exchanges in more detail.
