Linde can help you to stop the “oxygen leaks” Mc than you realize. You sit down and study oxygen prices before you buy it. A few cents loom large in your eyes at that time. Then, when oxygen is shipped in to your storehouse, you probably forget all about it. For one thing, you forget the oxygen valve in the top of the cylinder. It is the watchman of your oxygen supply. The Linde oxygen cylinder valve has a double seat. It prevents leaks whether it is open or closed. A glance at the diagram will show you why. But more important still is the waste of oxygen in use.
