It provides the correct thread and port transition between the gas valve and the furnace's gas supply\/manifold plumbing, ensuring a properly aligned, leak-free connection. Using the factory adapter avoids improvised bushings or mismatched threads that can leak gas or misalign the manifold.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 0259M00005\u003c\/li\u003e\n\u003cli\u003eApplication: Gas valve to manifold\/supply adapter fitting\u003c\/li\u003e\n\u003cli\u003eCompatibility: Amana\/Goodman AMH80403AXBD and related 80% furnaces\u003c\/li\u003e\n\u003cli\u003eFunction: Correct thread and port transition for the gas valve\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (Amana family)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGas-carrying fittings must match thread pitch, sealing surface, and length exactly. The OEM 0259M00005 is machined to the furnace's factory spec, so the gas valve seats square and torques to a reliable seal. Generic hardware-store adapters may have the wrong thread type or wall thickness — a serious safety risk on a live gas line. For any component in the gas path, OEM is the safe choice.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate (3\/5).\u003c\/strong\u003e Shut off the gas at the manual shutoff and cut power before starting. Use proper pipe-thread sealant rated for gas, torque to spec, and leak-test every joint with a soap-bubble solution before relighting. Because this is a live-gas repair, we strongly recommend a licensed HVAC technician perform the installation.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057601495411,"sku":"GOODMAN-4993","price":5.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-gas-valve-adapter-for-amh80403axbd-furnace-0259m00005","provider":"National HVAC Parts","version":"1.0","type":"link"}
