York S1-9951-1281 Orifice

York S1-9951-1281 Orifice

Maintaining 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, typically 3.5" W.C. in residential applications. For technicians servicing DGAM, DGAT, and DGRM series units, using a factory-spec manifold gas orifice is critical to prevent overfiring or underfiring of the burner assembly.

Poorly sized or clogged orifices can lead to incomplete combustion, soot buildup, and localized overheating of the heat exchanger. This brass component ensures clear gas delivery and proper aeration, sustaining the intended BTU output for the furnace. Whether you are performing a seasonal tune-up or a full gas valve replacement, installing a new natural gas burner orifice ensures the system operates within its original engineered parameters.

Key Benefits:
  • Precise Gas Flow Regulation: Provides a consistent flow rate for natural gas heating systems with a #30 drill size tolerance.
  • OEM Compatibility: Seamlessly replaces aged or fouled orifices in York HVAC gas furnaces and related brands like Coleman and Luxaire.
  • Durable Brass Construction: Resists thermal stress and corrosion within the burner compartment for reliable long-term performance.
  • Optimized Combustion: Helps maintain peak efficiency and reduces the risk of CO production due to improper fuel-to-air mixing.
Common Questions:
  • Can this orifice be used for Liquid Propane (LP) conversions? No, this is specifically sized for natural gas. LP requires a different orifice diameter due to the higher energy density and pressure requirements of propane.
  • How do I know if the #30 size is correct for my furnace? Verify the rating plate on the unit for the required orifice size based on your altitude and the specific manifold pressure.
  • What are the signs of a failing or incorrect orifice? Look for yellow flames, soot on the burners, or the furnace failing to meet its rated temperature rise, which often indicates improper gas flow or a partial blockage.
