Keep your furnace's condensate and drainage system leak-free with the genuine Goodman 10254303 rubber coupling, a direct-fit replacement for the Amana/Goodman AMH950704CXAF high-efficiency furnace. This flexible molded coupling forms a watertight, vibration-absorbing connection between drain or vent components, sealing the joint against condensate leaks that can corrode cabinet metal, trip float switches, or cause water damage around the equipment. Rubber that has hardened, cracked, or taken a set is a common source of nuisance drain leaks on 90%+ AFUE furnaces.
The OEM Goodman 10254303 is molded to the exact inner diameter and wall thickness your furnace requires, so it seats fully and seals without over-clamping. Generic rubber pieces are often undersized or made from lower-grade compounds that stiffen and leak sooner. For a small part that protects against water damage, OEM is inexpensive insurance.
Very Easy (1/5) — Slip off the old coupling, slide the new one into place, and secure with the existing clamps. No tools beyond a nut driver for the hose clamps. Inspect for a snug, leak-free fit and run the furnace through a heating cycle to confirm the drain stays dry.
