Hydrogen Testing

The Gascat valves that are used for pure hydrogen are tested on hydrogen in a large tank eight feet below water, thereby proving they are bubble-tight for hydrogen. Each one is then fitted with a ‘hydrogen tested’ label prior to use. Pictured above are two pure hydrogen valves: the fully stainless steel one is a 1″ Domus regulator and the other is a 1″ GIPS FC slam shut valve.
