This flexible rubber coupling joins condensate drain or trap connections and provides a watertight, vibration-tolerant seal between components. Over time rubber couplings harden, crack, or lose elasticity, leading to condensate drips, pressure-switch faults, and potential water damage — making this an inexpensive but important maintenance replacement.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart type: Rubber coupling \/ drain seal gasket\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GKS90453BXAB and related GKS90-series condensing furnaces\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas furnace (90%+ AFUE)\u003c\/li\u003e\n\u003cli\u003eMaterial: Flexible EPDM-type rubber, condensate-resistant\u003c\/li\u003e\n\u003cli\u003eFunction: Watertight connection for condensate drain \/ trap components\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 10254303\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine Goodman coupling is sized to the exact inner and outer diameters of the GKS90 drain ports, delivering a snug, leak-free seal. Generic rubber couplings from a hardware store may be close but rarely exact, and an imperfect fit on a condensate path invites slow leaks that are hard to trace. At this price, the correct OEM part is the smart choice.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (1 of 5).\u003c\/strong\u003e Power down the furnace, slide off the old coupling (loosen any hose clamps first), clean the mating surfaces, and press the new coupling into place. Re-tighten clamps and check for leaks after restarting.
