It provides a flexible, watertight connection at condensate drain and low-pressure venting joints, absorbing vibration while preventing leaks. On a 90%+ condensing furnace a sound coupling is critical — a cracked or hardened seal lets condensate escape, which can trip the pressure switch, corrode components, or cause water damage.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eGoodman OEM part number: 10254303\u003c\/li\u003e\n\u003cli\u003eComponent: Rubber coupling \/ connector seal\u003c\/li\u003e\n\u003cli\u003eMaterial: EPDM-type rubber\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas furnace (90%+ AFUE, condensing)\u003c\/li\u003e\n\u003cli\u003eFits model: GKS90905DXAD\u003c\/li\u003e\n\u003cli\u003eFit type: Direct exact-fit replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eCouplings must match the exact inside diameter and durometer to seal without deforming the mating parts. A generic coupling that is slightly over- or undersized can leak or split under heat cycling. The OEM 10254303 is dimensioned for Goodman's specific tubing, giving a reliable, long-lasting seal. For a low-cost part in a leak-critical location, OEM is the smart choice.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy.\u003c\/strong\u003e Usually under 10 minutes: power off the furnace, loosen the hose clamps, slide off the old coupling, fit the new one over both connections, and re-tighten the clamps evenly. Run the furnace through a heat cycle and check for any drips at the joint.\u003c\/p\u003e\u003cp\u003eExact-fit sourcing and fast shipping from NationalHVACParts.com.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058099437939,"sku":"GOODMAN-10874","price":2.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-rubber-coupling-for-gks90905dxad-furnace-10254303","provider":"National HVAC Parts","version":"1.0","type":"link"}
