This flexible coupling forms a leak-tight connection in the condensate drain and induced-draft\/vent assembly, absorbing vibration and thermal movement while preventing water and flue-gas leaks. A cracked or hardened coupling is a common cause of drain drips and pressure-switch faults, so replacing it with the correct OEM part restores reliable operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: 10254303\u003c\/li\u003e\n\u003cli\u003eType: Flexible rubber coupling \/ seal\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (OEM)\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas Furnace\u003c\/li\u003e\n\u003cli\u003eFits Model: GKS90453BXAA\u003c\/li\u003e\n\u003cli\u003eFunction: Leak-proof drain\/vent connection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine coupling is molded to the exact inside diameter and durometer Goodman specifies, so it seals correctly and resists condensate acidity. Off-brand rubber can be too stiff or too soft, leading to slow leaks or blow-off under draft pressure. At this price point, there is no reason not to use the OEM seal.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eVery Easy (1\/5).\u003c\/strong\u003e Typically a 5-minute, no-tools swap — slide the old coupling off and the new one on, seating it fully on both fittings.
