Rheem-Ruud 62-22175-50 Burner Orifice

The Rheem-Ruud 62-22175-50 Burner Orifice is a precision-engineered natural gas burner orifice designed for high-efficiency gas furnaces and heating units. Manufactured from durable brass, this OEM furnace replacement part features a #50 drill size (0.0700" diameter) to ensure exact fuel-to-air ratios for safe and stable combustion. With a 1/8-27 NPT thread size, 7/16-inch hex head, and a 9/16-inch overall length, this burner spud provides a leak-free seal and compatible flow rates for specific Rheem, Ruud, and Richmond equipment. As a veteran technician knows, maintaining the correct orifice drill index is critical to preventing weak flames, incomplete combustion, or carbon monoxide rollout. This individual component is essential for any service call involving burner manifold maintenance or fuel conversion adjustments where a natural gas orifice must meet original factory specifications for 1,000 to 1,050 BTU/ft³ fuel supplies.

• Precise Gas Metering: The #50 drill size ensures the manifold pressure generates the correct BTU output for specific burner stages.
• Durable Brass Construction: Corrosion-resistant material withstands heavy thermal cycling and prevents orifice fouling.
• OEM Compatibility: Guaranteed fit for Rheem and Ruud gas furnaces, eliminating the risks associated with universal "one-size-fits-all" spuds.
• Standardized Threading: The 1/8-27 NPT thread allows for direct installation into the burner manifold without additional adapters or field modifications.

What is the drill diameter for the 62-22175-50?
This orifice utilizes a #50 drill size, which corresponds to a precise 0.0700-inch diameter for optimized natural gas delivery.

Can I use this orifice for Propane (LP) conversions?
No, this specific part is sized for natural gas. LP applications require significantly smaller diameters due to higher energy density and manifold pressure; always consult the manufacturer’s conversion kit for the correct drill index.

How do I know if the orifice needs replacement?
Inspect for physical obstructions, soot buildup, or "rounding out" of the drill hole. If cleaning with compressed air does not restore a perfect round pinpoint of light, replacement is necessary to maintain proper flame signal and combustion efficiency.
