The Goodman 0259M00005 Gas Valve Adapter is a genuine OEM component engineered for Goodman and Amana gas furnaces, including the ACVC80803BXBC. This adapter provides the correct threaded interface between the gas valve and the manifold/supply line, ensuring a leak-free, code-compliant connection during gas valve service or replacement.
This is the factory OEM adapter, machined to exact thread and sealing tolerances. Unlike generic fittings, the OEM part guarantees proper alignment and gas-tight sealing, reducing the risk of leaks. Generic alternatives may require additional sealant or rework and can void furnace warranties.
Moderate — This is a gas-bearing component. Installation should be performed by a licensed HVAC technician. Gas supply must be shut off, the connection leak-tested with soap solution after assembly, and all work must comply with local gas codes.
Always confirm fitment against your furnace's parts diagram and rating plate before ordering.
