When it came to pressure gauge case production, the instrument industry primarily manufactured cases made from a brass substrate, which would then be plated with either chrome or gold.
But numerous other case materials were tested, including aluminum, titanium, solid gold, sterling silver, plastic, wood, and stainless steel, among other less common composites and alloys.
Of course, the sturdy and anti-corrosive properties of stainless steel were appealing to pressure gauge designers – as they were and continue to be for many pressure gauge designers around the world – but manufacturing cases with this material proved challenging.
Its stainless steel case and ring offer good appearance and excellent resistance to chemical, weather and corrosion attack.
