The Goodman 10254303 is a genuine OEM flexible rubber coupling designed for the WGFD293090V5DAB furnace and compatible Goodman/Amana units. This molded connector joins tubing runs — commonly on the inducer, condensate, or pressure-switch circuit — providing a vibration-dampening, airtight seal between components. Over time original couplings can harden, crack, or leak, causing pressure-switch faults or condensate seepage.
The OEM 10254303 is sized to the exact inside diameter of your Goodman tubing, ensuring a leak-free press fit without clamps working loose. Generic rubber couplings often run over- or undersized, leading to slow air leaks that trip the pressure switch and lock out the furnace. OEM ensures reliable sealing across heating cycles.
Slide the old coupling off, press the new one onto both tube ends, and confirm a snug fit. No tools required in most positions. Inspect adjoining tubing for cracks while you're in the unit.
