This flexible molded coupling joins and seals pipe or tubing connections — typically on the induced-draft\/vent or condensate drain path — absorbing vibration while keeping the joint air- and water-tight. A cracked, hardened, or split coupling can cause pressure-switch faults, flue-gas leaks, or water dripping around the furnace base.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 10254303\u003c\/li\u003e\n\u003cli\u003eType: Molded rubber coupling \/ seal\u003c\/li\u003e\n\u003cli\u003eMaterial: High-temperature EPDM-style rubber\u003c\/li\u003e\n\u003cli\u003eFunction: Vibration-dampening leak-tight connection\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas furnace\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GKS90905DXAA and compatible GKS9-series models\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM\u003c\/strong\u003e coupling is molded to the exact inside diameter and durometer Goodman specifies, ensuring a leak-free seal without over-clamping.
