Goodman 0259M00005 Gas Valve Adapter

The 0259M00005 is a genuine OEM gas valve adapter engineered for Goodman and Amana gas furnaces, including the AMEH800805DNAA. This fitting mates the gas valve to the manifold/inlet piping, ensuring a leak-free, code-compliant gas connection during burner operation. Using the factory adapter preserves the original thread pitch and sealing surface so your furnace fires reliably every heating cycle.

Specifications

OEM Part Number: 0259M00005
Type: Gas valve adapter / pipe fitting
Compatibility: Goodman & Amana furnaces incl. AMEH800805DNAA
Application: Gas manifold-to-valve connection
Material: Machined metal, natural gas & LP rated

OEM vs. Generic

The genuine OEM adapter guarantees an exact thread and seal match to your valve and manifold — critical for a gas-carrying joint. Generic or universal adapters may require re-taping, shimming, or additional fittings and can introduce leak points. For a safety-critical gas component we strongly recommend the OEM part.

Install Difficulty

Moderate (2/5). Replacement is straightforward with a pipe wrench and thread sealant, but any gas-line work must be leak-tested with soap solution and, where required by local code, performed or verified by a licensed HVAC technician. Always shut off gas and power before servicing.
