This self-acting

York S1-9951-1281 Orifice 321894-709 it provides consistent conductivity forMaintaining precise combustion on a manifold requires exact fuel to air ratios, and the York S1 9951 1281 Orifice is the key technical component for achieving that balance. This #30 (. 1285) Nat Gas Orifice is a genuine Source1 OEM replacement part designed specifically for York, Coleman, and Luxaire gas furnaces. Featuring a precision drilled 0. 1285 inch diameter, this orifice regulates the flow rate of natural gas at standard manifold pressures,
