The Goodman 0163M00049 is a genuine OEM hose clamp used throughout the AMSS921005CNAB gas furnace to secure condensate drain lines, inducer tubing, and pressure-switch hoses. A properly sized clamp keeps flexible hoses tight against their barbed fittings so the furnace holds vacuum and drains without leaks. Worn, over-stretched, or missing clamps are a frequent cause of loose hoses, air leaks that upset the pressure switch, and dripping condensate.
The OEM clamp is pre-sized to the exact hose outside diameters used on this furnace, delivering even clamping force without pinching or slipping. Generic hardware-store clamps may be the wrong band width or tension range, risking leaks or hose damage. For a clean, correct repair, choose the OEM clamp.
Easy (1/5) — A 5-minute job. Power down, slide the old clamp off, position the new clamp over the fitting, and secure. No tools beyond pliers or a nut driver required.
