what is the difference between a natural gas orifice and a propane orifice

by Monserrate Larson Published 5 years ago Updated 4 years ago

Natural gas orifices will have a wider opening since it is a lower pressure gas, but propane orifices will have a smaller hole because it is a compressed gas. They can’t be used interchangeably. You should never utilize a Natural Gas or Propane orifice drilled for Natural Gas on Propane or Propane for Propane.

Natural gas is fed at a smaller pressure than propane, so to get the same heating value (usually measured in BTUs), a natural gas orifice has to be smaller than a propane one. This suggests that you can convert a natural gas appliance to a propane one and vice versa by changing the orifice on the gas valve.
