A gas grill orifice is a small component in a gas grill that controls the flow of gas from the propane tank to the burners. It is typically located near the burners and can be adjusted to regulate the amount of gas that is released into the grill. The orifice works by restricting the flow of gas through a small hole, which allows for precise control over the flame. https://partsfe.com/grill-parts/gas-grill-orifice
