The Goodman 10254303 rubber coupling is a factory-specified sealing component used in the condensate drainage and vent assembly of the WFD195070S4CAA gas furnace and related Goodman/Amana models. A cracked, hardened, or missing coupling is a common cause of condensate leaks and pressure-switch faults, so replacing this small part restores a proper, leak-free seal.
The OEM Goodman 10254303 is molded to exact factory dimensions for a guaranteed seal and long service life. Generic couplings are lower-cost but often vary in durometer and diameter, which can lead to slow leaks or a loose fit. For a critical drainage/vent seal, OEM is strongly recommended.
