OEM vs. Generic

The OEM adapter is built to the exact thread pitch and dimensions of your furnace's gas train. Generic fittings risk cross-threading and gas leaks. For any component in the fuel line, the genuine part is the safe choice.

Install Difficulty

Moderate — the gas supply must be shut off and the joint pressure-tested (soap test) after installation. Pipe-thread sealant rated for gas is required. Recommended for experienced DIYers or a licensed technician.
