What is the drill size for the Rheem 62-22175-42?
This orifice is a #42 drill size, which corresponds to a physical diameter of 0.0935 inches.

Can I use this orifice for an LP conversion?
No, the 62-22175-42 is specifically sized for natural gas. High-pressure liquid propane requires a significantly smaller orifice diameter to prevent over-firing.

Will this fit standard 1/8-inch manifolds?
Yes, it utilizes a 1/8-27 NPT thread, which is the industry standard for most residential gas furnace burner orifices.
