The Goodman 0163M00049 Hose Clamp is a genuine OEM fastening component for the AMSS960403ANAA gas furnace and compatible Goodman/Amana models. It secures condensate, drain, and pressure-switch tubing to their barbed fittings, maintaining an airtight, leak-free connection. A slipped or corroded clamp is a common cause of drips, air leaks, and intermittent pressure-switch faults on condensing furnaces.
The genuine OEM clamp is sized to the exact hose diameter and clamping force used at the factory, ensuring a reliable seal without deforming the tubing. Generic clamps are often over- or under-sized, leading to leaks or crushed hoses. At this price point, using the correct OEM clamp is inexpensive insurance against callbacks.
Very Easy (1/5). Under 10 minutes with pliers or a nut driver. Power down the furnace, slide off the old clamp, position the new clamp over the hose and barb, and tighten to a snug — not crushing — fit. Confirm no leaks on the next cycle.
