The Goodman 0163M00049 Hose Clamp is a genuine OEM fastener used to secure condensate and drain hoses on the AMSS921005CNAA gas furnace and related Goodman/Amana models. Though small, this clamp plays a critical role: a loose or degraded clamp lets drain hoses slip, causing water leaks, condensate pooling, and pressure-switch trips that shut the furnace down.
This factory OEM clamp is sized precisely to your furnace's hose diameters, delivering consistent clamping force without crushing or under-gripping the tubing. Generic hardware-store clamps vary in bore and spring tension and can loosen with heat cycling, leading to slow leaks that are hard to diagnose. Genuine parts keep the repair reliable.
Very Easy (1 of 5). Replacement takes just a few minutes. Power off the furnace, remove the old clamp, seat the hose fully on its fitting, and secure the new clamp. Check for leaks after restoring condensate flow.
