The Goodman 10254303 Rubber Coupling is a genuine OEM connector for the Amana/Goodman AMVM961155DXBA modulating gas furnace. This flexible rubber coupling joins condensate drain or vent tubing sections, absorbing vibration while maintaining a watertight, leak-free connection. A hardened, cracked, or split coupling is a common source of condensate leaks and drain-line drips, so replacing it with the correct OEM part keeps the drainage system sealed and reliable.
The OEM coupling is sized to the exact inner and outer diameters of the furnace's factory tubing, giving a snug slip-fit that seals without extra clamps. Generic rubber couplings may be over- or undersized, leading to slow leaks and repeat callbacks. For a fast, watertight fit, choose the genuine part.
Easy — Slip the old coupling off, press the new one onto the tubing, and secure any clamps. A quick, inexpensive fix that prevents condensate leaks.
