Goodman 0259M00005 Gas Valve Adapter

The Goodman 0259M00005 is a genuine OEM gas valve adapter built as a direct-fit component for the ADSH800804BXAC furnace and compatible Goodman/Amana equipment. This adapter provides the correct threaded interface between the gas valve and the furnace manifold/supply, ensuring a leak-free, code-compliant gas connection and proper burner operation.

Specifications

Part number: 0259M00005
Type: Gas valve adapter / fitting
Function: Connects gas valve to manifold/supply line
Material: Machined metal fitting
Fit: Direct OEM replacement for ADSH800804BXAC
Application: Gas furnace fuel-train connection

OEM vs. Generic

The OEM 0259M00005 is machined to Goodman's exact thread specification and tolerances, so it mates cleanly with the factory gas valve and seals reliably. Generic adapters may have mismatched threads or finishes that risk gas leaks — an unacceptable outcome on a fuel-carrying component. We strongly recommend genuine OEM for anything in the gas train.

Installation Difficulty

Moderate (3/5). Requires shutting off the gas supply, disconnecting the valve, applying approved thread sealant, and torquing the adapter correctly, then leak-testing every joint; about 30 minutes. Gas-line work must be performed by a licensed HVAC or gas technician and leak-checked before restoring service.
