The Goodman 10254303 is a genuine OEM rubber coupling used to create a flexible, leak-free connection on the AMH950905DXAE furnace and compatible Goodman and Amana models. Rubber couplings like this join drain lines, condensate hoses, or inducer/pressure-switch tubing, absorbing vibration while maintaining an airtight and watertight seal. Over time the original rubber can harden, crack, or split — leading to condensate leaks or pressure-switch faults — making this an inexpensive, high-value maintenance replacement.
This genuine OEM coupling is molded to the exact inside diameter and durometer specified for your furnace, ensuring a snug, sealed fit. Generic couplings may be slightly off-size, leading to slow leaks or blow-offs under pressure. For a couple of dollars, OEM is the safe choice.
Very Easy (1 of 3). Slide off the old coupling and press the new one into place; secure any clamps. No tools required beyond a screwdriver for hose clamps.
