Hobart 819146 Pilot Orifice 1/4CC NAT

The Hobart 819146 Pilot Orifice is a gas-flow metering component used to control the fuel supply entering the pilot burner of compatible commercial cooking equipment. Its 1/4CC configuration and NAT designation identify the specified orifice size and natural-gas application. Installed within the pilot gas passage, the orifice creates a calibrated opening that limits the amount of gas delivered toward the pilot burner. This controlled flow supports formation of a steady pilot flame for igniting the main burner when required. The orifice works with pilot tubing, burner and gas-control components to regulate fuel delivery and maintain intended gas flow through the ignition system during operation.
