A pressure regulator for LP gas that is designed to reduce the pressure from the container to a lower pressure exceeding 1 psi is defined as a first stage regulator. This type of regulator is specifically utilized to manage high pressure coming from the gas container and adjusts it to a more usable intermediate pressure.

In LP gas systems, the first stage regulator is crucial because it acts as the initial reduction point, bringing down high container pressure to an intermediate level before it goes to the second stage regulator or directly to the appliance. This first stage handling of pressure is vital for safe and efficient gas distribution within a system.

By contrast, a second stage regulator is designed to further reduce that already lowered intermediate pressure to a final, lower operating pressure suitable for appliances, while a pressure reducing regulator may refer to any regulator that reduces pressure, not necessarily specifying high to low. Bypass regulators typically refer to a different function, where they allow for excess flow to bypass and maintain function even with fluctuations.
