The Goodman 10254303 Rubber Coupling is a genuine OEM sealing component for the WGFD293090V5DAA gas furnace and compatible Goodman/Amana models. This flexible coupling creates an airtight, watertight connection between furnace tubing sections — commonly on the inducer, pressure-switch, or condensate drain circuits. A cracked or hardened coupling causes air leaks that trip the pressure switch or allow condensate seepage.
Generic couplings often use the wrong inside diameter or a rubber compound that hardens quickly under furnace heat, leading to slow leaks and repeat failures. This OEM 10254303 matches Goodman's exact dimensions and is rated for the temperature and moisture of high-efficiency furnace operation.
Easy (1/5) — Power down the furnace, loosen the hose clamps, slide off the old coupling, fit the new one, and re-tighten the clamps. A 5–10 minute repair with a nut driver or screwdriver. Confirm your model number before purchasing.
