Armstrong Air 22W53 Gas Orifice

Product Description

The ARMSTRONG AIR 22W53 is a gas orifice used in residential and light commercial gas furnace burner assemblies. The orifice meters the flow of gas from the manifold into the burner tube, directly affecting combustion efficiency and heat output. Proper orifice sizing is critical to safe, code-compliant operation. At approximately 0.03 pounds, this is a small but precision-machined component. Installation is typically performed by a licensed HVAC technician or gas fitter during routine maintenance, burner conversion, or combustion tuning work.

This orifice is designed for use in gas furnace applications where the burner assembly requires replacement or rejet service. It is appropriate for residential forced-air gas heating systems. When a furnace is converted between natural gas and propane, or when a burner orifice is found to be damaged or out of spec, this part provides an OEM-style replacement solution. Always verify the orifice size matches the fuel type and BTU rating required by the equipment nameplate before installation.

Key Features

• Precision-machined orifice for accurate gas metering at the burner
• OEM-style replacement for gas furnace burner assemblies
• Lightweight at 0.03 pounds for easy handling during service
• Critical fit component - size must match fuel type and manifold pressure requirements

Compatibility

Designed as an OEM-style replacement gas orifice for residential and light commercial gas furnace burner assemblies. Verify orifice size and fuel type compatibility against the unit nameplate before installation.

Installation Notes

Gas orifice replacement should be performed by a licensed HVAC technician or gas fitter in accordance with local codes and the IFGC. Shut off the gas supply and disconnect electrical power to the furnace before beginning any burner or manifold service. Do not overtighten the orifice fitting, as the threads on brass fittings can strip or crack the manifold. After installation, perform a leak test at the manifold and verify combustion before returning the unit to service.
