Orifice Comparison. An orifice is the opening in the fuel line that feeds your grill's burners. The orifice composition is not significantly different between propane and gas grills. In both cases it is generally made of brass and is threaded to fit the end of a fuel hose.f you convert your propane grill to natural gas, the control valve may not supply enough heat through the orifice, even if the orifice is the correct size. The regulator controls the pressure of the fuel and differs between propane and natural gas. This must be converted only by a licensed professional.
