The orifice threads into the manifold and meters the exact gas flow to each in-shot burner. A cracked, over-drilled, or debris-clogged orifice causes weak flames, incomplete combustion, or delayed ignition.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: B4089343\u003c\/li\u003e\n\u003cli\u003eOrifice size: #43 drill (natural gas)\u003c\/li\u003e\n\u003cli\u003eThread: Standard manifold spud thread\u003c\/li\u003e\n\u003cli\u003eMaterial: Brass\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana DHS80704BXA and related 80% furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGas orifice sizing is a safety-critical dimension — the #43 bore is matched to the furnace's manifold pressure and BTU rating. OEM orifices are precision-drilled and deburred so each burner receives identical gas flow. A mis-sized generic spud can cause sooting or overheating. Always match the drill number stamped on the part.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy to Moderate\u003c\/strong\u003e — Shut off gas, remove the manifold or back out the spud with a nut driver, and hand-tighten the replacement.
