OEM vs. Generic

Gas connections must match thread type, size, and pressure rating exactly. The OEM adapter is machined to the furnace manifold spec, so it seats and seals as designed. A mismatched generic fitting risks cross-threading and gas leaks—use the factory part for any fuel connection.

Install Difficulty

Moderate (3/5). Involves opening a gas connection; shut off the gas supply, use approved thread sealant, and leak-test with soap solution before firing. If you are not comfortable working on gas lines, hire a licensed technician.
