Goodman 0259M00005 Gas Valve Adapter

The 0259M00005 is a genuine OEM gas valve adapter for Goodman ADSH800603AXAC gas furnaces and compatible models. This machined fitting adapts the gas valve outlet to the manifold, ensuring a leak-free, thread-matched connection between the valve and burner supply. Using the correct factory adapter is essential for safe gas delivery and proper manifold pressure.

Specifications

  • OEM Part Number: 0259M00005
  • Type: Gas valve / manifold adapter fitting
  • Application: Gas valve-to-manifold connection
  • Material: Machined metal fitting
  • Fits: Goodman ADSH800603AXAC and select Goodman/Amana furnaces

OEM vs. Generic

The OEM Goodman adapter is threaded and dimensioned to the exact valve and manifold spec, so it torques down gas-tight without shims or thread damage. Generic fittings risk cross-threading and slow leaks on a fuel line — not a place to cut corners. We recommend OEM for any gas-carrying component.

Installation Difficulty: Moderate

Rated 3/5. Gas-line work should be performed by a qualified technician. Shut off gas at the valve, apply approved pipe sealant, torque to spec, and leak-test every joint with a bubble solution before firing. When in doubt, hire a licensed HVAC pro.

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?

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.
