Goodman 10254303 Rubber Coupling

The 10254303 rubber coupling is a genuine OEM sealing connector for the Goodman GMH950453BXAE 95% AFUE gas furnace. In high-efficiency condensing furnaces, flexible rubber couplings join inducer, pressure-switch tubing, and condensate/drain connections, creating an air- and water-tight seal that keeps the pressure-switch circuit accurate and prevents leaks. Over time rubber hardens, cracks, and loses its seal — leading to pressure-switch faults, gurgling, or condensate drips. This exact-fit OEM coupling restores a clean seal.

Specifications

OEM Part Number: 10254303
Type: Molded rubber coupling / sealing connector
Fits: Goodman GMH950453BXAE and compatible GMH95 furnaces
Equipment Type: High-Efficiency Gas Furnace
Material: Heat- and moisture-resistant molded rubber (EPDM-type)
Application: Inducer / pressure-switch / condensate connection seal

OEM vs. Generic

The OEM Goodman coupling is molded to the precise diameter and durometer needed for a leak-free fit on your furnace. Generic hose or tubing may be close in size but often seals poorly or degrades quickly under heat and moisture, causing recurring pressure-switch trips. For a reliable seal, OEM is worth it — especially at this low price.

Install Difficulty

Very Easy (1/5) — Slip the old coupling off, push the new one on, and confirm a snug fit on both ends. Under 5 minutes. Power and gas off before servicing.
