The Goodman 0259M00005 Gas Valve Adapter is a genuine OEM fitting used to properly mate the gas valve to the manifold/gas train on the ADSH800603AXAB furnace. It ensures correct thread engagement and orientation so the valve seats square and delivers a leak-free, code-compliant gas connection.

Specifications

  • Application: Gas valve to manifold adapter fitting
  • Function: Correct valve alignment and sealed gas connection
  • Material: Machined metal fitting
  • OEM Part Number: 0259M00005
  • Primary Fit: Goodman ADSH800603AXAB furnace

OEM vs. Generic

Because this adapter carries live natural gas or propane, the genuine OEM 0259M00005 is the safe choice — its thread pitch, length, and sealing surface are machined to Goodman spec so the valve tightens to the correct depth. Generic fittings can bottom out early or leave the valve misaligned, creating gas-leak hazards. For any gas-carrying component, always use OEM.

Install Difficulty

Moderate (3/5). Gas-line work should be done by a qualified technician. Shut off the gas supply, disconnect the valve, apply approved gas-rated thread sealant, install the adapter to spec, then leak-test every joint with soap solution or a gas detector before firing the furnace.

How do I replace the gas valve on my Goodman ADSH800603AXAB — 0259M00005?

What symptoms mean I need a new gas valve?
Common symptoms: unusual noises, intermittent operation, complete failure, or visible damage. Visit our diagnostic hub for symptom-based troubleshooting.
Is this gas valve compatible with Bryant or Payne too?
Many Goodman parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Goodman gas valve?
Always use OEM. Gas valves must match exact pressure ratings, port configurations, and safety certifications. Non-OEM gas valves can create safety hazards and may violate building codes.
