What is a typical working pressure of LP gas after the pressure regulator?

The typical working pressure of liquid propane (LP) gas after passing through the pressure regulator is around 0.4 PSI. At this pressure level, the gas is safely delivered to appliances designed for LP gas use, ensuring that the appliances function efficiently and reliably while minimizing the risk of dangerous over-pressurization.

Understanding the pressure regulator's role is key; it reduces the higher pressure of the gas in the storage tank to a lower, usable pressure for appliances. This regulation ensures consistent performance across various devices, such as stoves and heaters, which rely on the proper delivery of gas at a defined pressure.

The other pressures listed in the choices are not typical for the post-regulator stage in LP gas systems. For example, pressures like 14 PSI or 50 PSI are more aligned with high-pressure systems or bulk storage setups, which are not suitable for everyday residential or commercial appliance use, as they could lead to hazards if not properly managed.
