The Goodman 10254303 is a genuine OEM rubber coupling used to create a leak-free seal between drain, condensate, and vent connections inside Goodman 90%+ AFUE gas furnaces such as the GMS950453BXA. Over time, factory couplings can dry out, crack, or take a set, allowing water to weep from the collector box or inducer drain and eventually tripping the pressure switch. Replacing this small part restores a tight seal and prevents nuisance lockouts and cabinet corrosion.
The OEM 10254303 is molded to exact factory tolerances for a guaranteed slip-fit and long service life. Our generic equivalent matches the critical dimensions and temperature rating at a lower price point — a solid choice for budget-minded repairs where an exact OEM match is not required.
Easy (1/5). No tools required in most cases — power down the furnace, slide off the old coupling, and press the new one into place. Typically a 5-minute repair for a homeowner or technician.
Always confirm compatibility with your model and serial number before ordering. Repairs involving gas appliances should be performed by a qualified HVAC technician where required by local code.
