Description
The BASO Gas Products Y90AA-3218 Pilot Orifice controls natural gas flow supplied to the pilot burner assembly during operation. This component regulates fuel delivery by allowing a measured amount of gas to pass through the pilot pathway for proper ignition support. It operates through a 0.018″ opening with a 1/4″ compression coupling connection to match the required gas control setup. The part is installed within compatible gas-fired equipment and HVAC systems during service or replacement work. It helps maintain accurate pilot fuel flow and supports the required burner ignition process.
