Goodman 10254303 Rubber Coupling

The Goodman 10254303 is a factory OEM rubber coupling used to join and seal drain or vent tubing on the GMH950904CXAD 96% AFUE two-stage gas furnace. This flexible elastomer connector creates a leak-tight, vibration-tolerant joint between the collector box, condensate trap, and drain/vent lines. Rubber couplings harden and split over years of exposure to acidic condensate and heat, so a fresh seal restores a proper watertight and airtight connection.

OEM Part Number: 10254303
Type: Rubber coupling / connector seal (gasket seal)
Material: Heat- and condensate-resistant rubber/EPDM
Function: Leak-tight, flexible joint for drain / vent tubing
Compatibility: Goodman GMH950904CXAD and related GMH95 furnaces

OEM vs. Generic

The genuine Goodman coupling matches the exact inside diameter and durometer needed to seal your furnace's tubing without clamps slipping or the rubber over-compressing. Generic couplings may be the wrong size or a lower-grade rubber that degrades quickly, leading to condensate leaks. At this price point, OEM is the easy choice.

Installation Difficulty

Easy (1/5). Loosen the hose clamps, slide off the old coupling, fit the new one, and re-tighten. Under 10 minutes with a screwdriver or nut driver. Turn off power and gas before servicing, then confirm no leaks on the next heat cycle.
