The Goodman 10254303 Rubber Coupling is a genuine OEM sealing component for the GKS90904CXAF high-efficiency gas furnace and related Goodman/Amana models. This flexible EPDM-style coupling creates a leak-free, vibration-dampening connection between condensate, drain, or vent components inside the furnace cabinet. On a 90%+ condensing furnace, a proper seal here prevents water leaks, flue-gas escape, and pressure-switch faults that can lock out the entire system.

Specifications

Type: Molded rubber coupling / grommet seal
Material: Heat- and moisture-resistant synthetic rubber
Function: Condensate / drain / vent connection seal and vibration isolation
Fits: Goodman GKS90904CXAF and compatible condensing furnaces
Brand: Goodman OEM (Amana compatible)

OEM vs. Generic

The genuine 10254303 is molded to the exact inner and outer diameters of the factory ports, so it seats fully and seals on the first push. Generic rubber grommets that are close-but-not-exact tend to weep condensate, slip under vibration, or degrade prematurely when exposed to acidic flue condensate. At this price point, the OEM part is the obvious choice for a reliable, long-lasting seal.

Installation Difficulty

Very Easy (1/5) — Power down the furnace, remove the old coupling, clean the mating surfaces, and press the new one into place. No tools or sealant typically required. A quick, low-risk maintenance item.
