0.021 in. Natural Gas Pilot Orifice Cup

An orifice is any opening, mouth, hole or vent, as in a pipe, tube or a plate used to either regulate or measure the intake or output of a gas or liquid, e.g. "air orifice", or "orifice plate".

A pilot light is a small gas flame, usually natural gas or liquefied petroleum gas, which serves as an ignition source for a more powerful gas burner. In a pilot assembly, there is thermocouple sitting in the pilot light's flame. The electricity that is created from the flame contacting the thermocouple wire runs to a small electromagnetic valve and holds it open. If the pilot light blows out, the thermocouple quickly cools off. It stops generating electricity and the valve closes.
