Goodman 0259M00005 Gas Valve Adapter

The 0259M00005 is a genuine Goodman/Amana gas valve adapter fitting engineered for the AMEH800805CNAB gas furnace and other compatible Goodman-family models. This adapter provides the precise thread pitch and sealing surface needed to mate the gas valve to the manifold or supply line, ensuring a code-compliant, leak-free connection. Because gas-carrying components have zero tolerance for improvised parts, using the OEM-spec adapter is the safest and most reliable choice.

Specifications

OEM Part Number: 0259M00005
Brand: Goodman / Amana
Component Type: Gas valve adapter fitting
Fits: AMEH800805CNAB and compatible Goodman-family furnaces
Application: Natural gas / LP furnace gas train
Material: Machined metal with sealed thread interface

OEM vs. Generic

Our OEM 0259M00005 is built to Goodman's exact dimensional and thread specifications, guaranteeing a proper gas-tight seal on the first install. Generic aftermarket adapters may vary in thread depth or seat geometry, risking slow gas leaks that are both dangerous and difficult to diagnose. For a gas-side component we strongly recommend OEM.

Installation Difficulty

Moderate — HVAC/gas professional recommended. Any work on the gas train should include shutting off the gas supply, applying approved thread sealant where specified, and performing a leak check with a soap/bubble test or manometer before returning the furnace to service. If you are not comfortable working on gas connections, hire a licensed technician.

Compatibility note: Verify the part number against your unit's rating plate or exploded parts diagram before ordering.
