The Goodman 0163M00049 hose clamp is a genuine OEM fastener used throughout the AMVC961005CNBA gas furnace to secure condensate drain hoses and pressure-switch tubing to their collector-box and trap ports. Though small, a proper clamp is essential: it maintains the airtight, leak-free connections the furnace's draft-proving and drainage systems depend on.
Over time, factory clamps can corrode, lose tension, or crack during service. A loose clamp can allow a hose to slip, causing pressure-switch lockouts, water leaks, or condensate backup — problems easily avoided with the correct OEM replacement.
The OEM 0163M00049 is sized to the furnace's specific hose diameters and clamping range, ensuring a secure seal without crushing the tubing. Off-size hardware-store clamps can under- or over-tighten and leak. OEM guarantees the right fit for reliable connections.
Slide the clamp over the hose, seat it on the port, and tighten to a snug seal. No tools beyond a nut driver or pliers are needed. A quick 5-minute job, ideal to replace whenever a hose is disturbed.
