Q. Which regulator is best for gas?

Answer

The characteristics and degree of cleanliness of the gas being regulated should guide the selection of the components used in the design of a regulator. Brass, aluminum, and stainless steel 316L are the three most common metals used in the production of regulators. Brass is compatible with the vast majority of the gases that do not react. The option of purchasing either a forged body or a barstock construction. If a regulator that only works with one type of cylinder valve, won't be able to use it with any of the others since each regulator is tailored to match a particular variety of cylinder valves.
