OEM vs. Generic

Because this component carries fuel gas under pressure, thread pitch and dimensional accuracy are critical. The OEM Goodman adapter is machined to match your valve and manifold exactly. Generic substitutes risk cross-threading and gas leaks — we strongly recommend the OEM part for any gas-carrying fitting.

Installation Difficulty

Moderate — Requires shutting off the gas supply, applying approved pipe sealant/thread compound, and leak-testing the connection after assembly. This work involves the fuel-gas circuit and should be completed by a licensed HVAC or gas technician; plan for 20–40 minutes including leak checks.
