The Goodman 0163M00049 hose clamp is a genuine OEM fastener used throughout the AMSS960402BNAA high-efficiency furnace and related Goodman/Amana condensing models. This clamp secures condensate drain hoses and pressure-switch tubing to their barbed fittings, ensuring a leak-free, vibration-resistant connection. A loose or degraded clamp can allow a hose to slip, causing water leaks, air leaks in the pressure circuit, and intermittent furnace lockouts.
OEM vs. Generic: The factory clamp is sized to the exact hose OD and barb diameter used on Goodman furnaces, applying even clamping force without crushing the tubing. Generic hardware-store clamps are often over- or undersized, which can pinch hoses or fail to seal the low-pressure sensing lines that the furnace's safety circuit depends on.
Install difficulty: Easy (1/5). Slide the clamp over the hose, seat the hose fully on the barb, and tighten or clip into place. A single flat-blade screwdriver is all that's needed for worm-gear versions. Replace clamps whenever you service condensate hoses to avoid repeat leaks.
Keeping tubing connections tight is critical on condensing furnaces, where the pressure-switch circuit and condensate path directly affect ignition and safe operation. Confirm the part number against your unit before ordering.
