Description
A small metal fitting called an Orifice #33 Natural Gas Sterling Patio TEC Grills, often made of brass or stainless steel, is what the orifice is actually composed of. It is designed to have a precise opening that enables the regulated release of natural gas. Orifice #33, in this instance, denotes a certain size or diameter of the orifice opening, which is precisely calibrated to fit the gas pressure and burner specifications of TEC Grills using natural gas.
