Genuine Goodman 10254303 Rubber Coupling

The Goodman 10254303 rubber coupling is a factory OEM sealing component for the GKS90905DXAD high-efficiency gas furnace. It provides a flexible, watertight connection at condensate drain and low-pressure venting joints, absorbing vibration while preventing leaks. On a 90%+ condensing furnace a sound coupling is critical — a cracked or hardened seal lets condensate escape, which can trip the pressure switch, corrode components, or cause water damage.

Specifications

Goodman OEM part number: 10254303
Component: Rubber coupling / connector seal
Material: EPDM-type rubber
Equipment: Gas furnace (90%+ AFUE, condensing)
Fits model: GKS90905DXAD
Fit type: Direct exact-fit replacement

OEM vs. Generic

Couplings must match the exact inside diameter and durometer to seal without deforming the mating parts. A generic coupling that is slightly over- or undersized can leak or split under heat cycling. The OEM 10254303 is dimensioned for Goodman's specific tubing, giving a reliable, long-lasting seal. For a low-cost part in a leak-critical location, OEM is the smart choice.

Install Difficulty

Easy. Usually under 10 minutes: power off the furnace, loosen the hose clamps, slide off the old coupling, fit the new one over both connections, and re-tighten the clamps evenly. Run the furnace through a heat cycle and check for any drips at the joint.
