Rheem-Ruud 62-22175-43 Burner Orifice

The Rheem-Ruud 62-22175-43 Burner Orifice is a critical precision component for technicians maintaining or configuring natural gas furnace systems. Engineered for high-efficiency gas combustion, this brass burner orifice features a #43 drill size (0.0935-inch diameter) to ensure the exact manifold pressure and BTU input required for optimal burner performance. With a 7/16-inch hex head size and an overall length of 9/16 inches, it provides a secure fit in the manifold assembly. As a genuine OEM replacement part, it is compatible with a wide range of Rheem and Ruud equipment, including R801P-MSA and MXA series gas furnaces, ensuring local code compliance and preventing issues like undershooting or overfiring that lead to soot buildup and heat exchanger stress.

• Precision Metering: The #43 drill diameter allows for exact gas flow control, maximizing combustion efficiency in the heat exchanger.
• OEM Compatibility: Designed specifically for Rheem-Ruud systems to maintain original equipment certification and safe furnace operation.
• Durable Brass Build: Resists thermal expansion and corrosion, maintaining strict tolerances under extreme furnace burner temperatures.
• Exact Specifications: Features standard 1/8-27 NPT threading for a reliable, leak-free connection to the gas manifold.

What is the drill size for the 62-22175-43 orifice?
This orifice is a #43 drill size, which corresponds to a 0.0935-inch decimal diameter, standard for many residential natural gas burner applications.

Can I use this orifice for an LP gas conversion?
No, this is specifically a natural gas orifice. Converting a furnace from natural gas to LP requires a specific conversion kit with smaller orifices due to the higher BTU content of propane.

Why is selecting the correct orifice size so important?
Using an incorrect size can lead to improper gas-to-air ratios, potentially causing high carbon monoxide levels, burner "hunting," or premature failure of the ignition components.
