The Goodman 10254303 is a factory OEM rubber coupling used on the AMVC950905DXAC condensing furnace and compatible Goodman/Amana models. It creates a flexible, watertight connection between drain and condensate components, absorbing vibration while preventing leaks at the joint.
This genuine OEM coupling is molded to the exact diameter and durometer of the factory part, ensuring a proper seal. Generic rubber couplings may be close but rarely match perfectly, leading to slow condensate leaks that can trigger pressure-switch faults. For a small part with a big job, OEM is worth it.
Easy (1/5). No tools needed in most cases — disconnect power, slip off the old coupling, and press the new one into place. A dab of approved lubricant eases installation. Typically done in under 5 minutes.
