On high-efficiency furnaces, flexible rubber couplings join condensate drain and pressure-sensing tubing to induced-draft and collector-box connections, maintaining an airtight, leak-free seal. Over time rubber hardens, cracks, or loosens — leading to pressure-switch faults, condensate leaks, and intermittent ignition lockouts. Replacing this inexpensive part often clears frustrating no-heat problems.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 10254303\u003c\/li\u003e\n\u003cli\u003eType: Flexible rubber coupling \/ tubing seal\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMV951155DXA and compatible condensing furnaces\u003c\/li\u003e\n\u003cli\u003eMaterial: Molded EPDM-style rubber for heat and moisture resistance\u003c\/li\u003e\n\u003cli\u003eFunction: Airtight\/watertight connection for condensate and pressure lines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGenuine Goodman couplings are molded to the precise inner diameter and durometer of the original, so they seat snugly and seal completely. Loose or ill-fitting generic rubber can allow tiny air leaks that fool the pressure switch and trigger nuisance shutdowns.
