The Goodman 10254303 Rubber Coupling is a genuine OEM sealing component for the AMH950453BXAA furnace. This flexible coupling creates a leak-tight, vibration-dampening connection between the inducer/venting and condensate components. A cracked or hardened coupling can cause air leaks, pressure-switch faults, and condensate seepage — replacing it restores a proper seal.
Genuine OEM rubber is molded to the exact inner diameter and durometer required for a tight seal. Generic couplings may not match the fitting size, leading to slow leaks and repeat failures. This inexpensive OEM part is cheap insurance against nuisance pressure-switch lockouts.
Easy (1/5). Slip-on coupling, often secured with spring clamps. Power and gas off before servicing. Inspect mating surfaces for debris before reassembly.
