The Goodman 10254303 Rubber Coupling is a genuine OEM sealing coupling for the GMH951155DXAA 95% AFUE gas furnace. Used to join condensate/drain and inducer tubing connections, this flexible coupling creates a leak-tight seal while absorbing vibration between components. A cracked or hardened coupling can cause condensate leaks, pressure-switch faults, or nuisance lockouts — a quick, inexpensive part to keep a high-efficiency furnace running clean and dry.
