This flexible coupling joins condensate or vent-line sections and forms a tight, vibration-tolerant seal that prevents water and flue-gas leakage. In a condensing furnace, even a small leak at a coupling can allow acidic condensate to drip onto the burner box or cabinet, causing corrosion and premature failure — so a correctly sized, correctly graded seal matters.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 10254303\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Gasket \/ seal (rubber coupling)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman GMH950905DXAD furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Condensate-rated flexible rubber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Leak-free connection between drain\/vent sections\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit type:\u003c\/strong\u003e Direct OEM exact-fit replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e Hardware-store rubber couplings vary in inside diameter, wall thickness, and chemical resistance.
