OEM Goodman 0259M00005 Gas Valve Adapter

The Goodman 0259M00005 is a genuine OEM gas valve adapter for the Amana/Goodman AMH81005CNBD gas furnace. This precision-machined fitting adapts the gas valve outlet to the burner manifold (or supply line), providing the correct thread pitch and seating surface for a leak-tight, code-compliant gas connection.

Specifications

Function: Gas valve-to-manifold adapter fitting
Material: Machined metal, gas-rated threads
Compatibility: Amana & Goodman AMH81005CNBD furnace gas train
Use: Connects combination gas valve to manifold/supply
OEM Part Number: 0259M00005

OEM vs. Generic

Because this adapter is part of a fuel-carrying connection, thread type and sealing surface must be exact. The OEM 0259M00005 matches the furnace's gas train precisely. Hardware-store fittings may have the wrong thread standard or sealing profile, risking gas leaks — OEM is strongly recommended for any component in the gas path.

Install Difficulty

Moderate (3/5) — Involves opening the gas connection, applying approved pipe sealant, and pressure/leak-testing the joint with a bubble solution afterward. This work should be performed by a licensed HVAC or gas technician. Always shut off gas and power before servicing.
