Replace a cracked, hardened, or leaking connection on your Goodman GKS91155DXAB gas furnace with the genuine OEM 10254303 rubber coupling. This flexible EPDM-style coupling forms a leak-tight seal between condensate drain, inducer, or pressure-tap components while absorbing vibration to prevent noise and stress cracking. Over time, factory couplings dry out and split, causing condensate leaks or pressure-switch faults — a quick, inexpensive replacement restores a proper seal.
The genuine OEM coupling is molded to the exact inner and outer diameters required by the GKS91155DXAB, guaranteeing a snug, leak-free fit. Generic couplings may be slightly off-size, leading to slow leaks or blow-off under pressure. For a reliable seal, choose the factory-matched part.
Very Easy (1/5) — Loosen the hose clamp(s), slide off the old coupling, and press the new one into place. No tools beyond a nut driver required. Power down the furnace before servicing.
