Goodman 10254303 Rubber Coupling

This genuine OEM Goodman 10254303 rubber coupling is a sealing/connecting fitting used in the condensate and induced-draft plumbing of the Goodman/Amana AMV90704CXBA 90%+ AFUE condensing furnace. Because a 90% furnace produces acidic condensate, the couplings that join drain hoses, traps, and collector-box ports must stay flexible and leak-tight. Rubber couplings harden and crack with age and heat cycling, causing water leaks, condensate spillage, and pressure-switch faults — this OEM part restores a proper seal.

Specifications

Type: Flexible rubber coupling / hose seal
Material: Molded EPDM-style rubber (condensate-resistant)
Application: Condensate drain / draft plumbing connection
Fits: Goodman & Amana AMV90704CXBA and related condensing furnaces

OEM vs. Generic

OEM 10254303 is molded to the exact inner/outer diameters of this furnace's ports and hoses for a tight, drip-free connection. Generic couplings often differ slightly in size or wall thickness, leading to slow leaks or blow-off under draft pressure. For a low-cost part that prevents water damage and nuisance shutdowns, the OEM fit is worth it.

Installation Difficulty: Easy

Slip the old coupling off, seat the new one fully on both fittings, and secure any clamps — a 10-minute job with no special tools. Power and gas off first. After install, run the furnace and confirm the drain path is leak-free and the trap is primed.
