The genuine Goodman 0163M00049 Hose Clamp secures the condensate and pressure-switch tubing connections on the ACVM970804CNAA furnace and compatible Goodman/Amana models. Though small, the correct clamp is essential: a loose or degraded clamp allows condensate hoses or pressure tubing to slip, causing leaks, pressure-switch errors, and nuisance lockouts. Replacing brittle or over-tightened clamps during routine service prevents callbacks.
OEM clamps are sized to the exact hose outer diameter used on the ACVM970804CNAA, providing even clamping pressure without crushing the tubing. Generic hardware-store clamps can be the wrong diameter or apply uneven force, leading to slow leaks. For a few cents difference, OEM is the reliable choice.
Very Easy — under 5 minutes. Slide the new clamp over the hose, position it on the fitting, and tighten. No tools beyond a nut driver or pliers required. A common maintenance item to keep on hand.
