The Goodman 0163M00049 hose clamp is a genuine OEM fastener used throughout the AMVM970804CNAA variable-speed gas furnace to secure condensate drain hoses and pressure-switch tubing to their barbed fittings. A loose or aged clamp lets tubing slip or leak, which can trigger pressure-switch faults and water damage — so keeping fresh clamps on hand is smart for any condensate or induced-draft service.
The genuine OEM clamp is sized to the exact hose outer diameters used in the AMVM97, providing a reliable seal without crushing the tubing. Off-size hardware-store clamps may under- or over-tighten, leading to slow leaks or pinched hoses.
Easy (1/5) — Squeeze or unscrew the old clamp, slide it off, and fit the replacement over the hose and fitting. A quick 5-minute task with pliers or a nut driver.
