For brazed joints in medical gas piping, what is used to test them?

Explanation:
When testing brazed joints in medical gas piping, a gas that is inert, dry, and non-flammable is used. Nitrogen fits this role perfectly, providing a safe medium to pressurize the system to the required test pressure without introducing reactive components or moisture. This helps reveal leaks reliably while minimizing oxidation or moisture-related issues that could mask leaks. Using air would bring in oxygen and humidity, which can cause corrosion and complicate leak detection, and oxygen itself isn’t inert. Helium could detect smaller leaks more easily, but it’s more expensive, so nitrogen is the practical, standard choice.
