This flexible coupling connects and seals condensate drain, inducer, or pressure-tubing junctions, maintaining an airtight and watertight bond between components. Over years of thermal cycling, rubber couplings can harden, crack, or leak — leading to pressure-switch faults, condensate leaks, or nuisance lockouts. Replacing a worn coupling with the correct OEM part restores proper drainage and combustion-air sealing.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Flexible rubber coupling \/ seal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Airtight\/watertight junction seal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Molded rubber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e GKS90904CXAA and compatible Goodman furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman (OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e Couplings are inexpensive, so there is little reason to gamble on a generic that may not match the exact inside diameter or durometer. An improperly sized aftermarket coupling can leak or slip off, causing recurring service calls. The OEM 10254303 fits precisely the first time.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstall Difficulty:\u003c\/strong\u003e Very easy — a 5–10 minute replacement requiring no special tools. Turn off power to the furnace, slide off the old coupling, and press on the new one. A great low-cost part to keep on hand during any furnace tune-up.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058093900147,"sku":"GOODMAN-10747","price":2.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-rubber-coupling-for-gks90904cxaa-furnace-10254303","provider":"National HVAC Parts","version":"1.0","type":"link"}
