Goodman 10254303 Rubber Coupling

The Goodman 10254303 rubber coupling is a genuine OEM sealing component for the GMH950453BXAC 95% AFUE gas furnace. This flexible coupling joins condensate, drain, or inducer/pressure tubing connections and forms an airtight, watertight seal. A cracked or hardened coupling is a common cause of condensate leaks and pressure-switch faults, so replacing it with the factory part restores a proper seal and correct pressure signals.

Specifications

OEM Goodman part number: 10254303
Component: Rubber coupling / sealing grommet
Material: Flexible high-temperature EPDM-type rubber
Compatible model: GMH950453BXAC (95% AFUE furnace)
Function: Airtight / watertight tubing connection seal

OEM vs. Generic

Generic rubber couplings often use the wrong inside diameter or a rubber compound that degrades under furnace heat, leading to repeat leaks. This genuine Goodman coupling is sized and compounded to factory spec for a lasting, drip-free seal.

Install Difficulty

Easy (1/5). Slide off the old coupling and press the new one onto the fitting — no tools required in most cases. Inspect adjacent tubing for wear while you have access.

Shut off power and gas before servicing. If leaks or pressure faults persist, consult a licensed HVAC technician.
