The genuine Goodman 0163M00049 Hose Clamp is a factory replacement fastener for the ACSS921005CNAA gas furnace. This clamp secures condensate, drain, and pressure-switch hoses to their barbed fittings, maintaining the tight, leak-free connection a condensing furnace needs for proper drainage and accurate pressure sensing. A corroded or sprung clamp lets hoses slip or weep, leading to water leaks, pressure-switch faults, and nuisance lockouts.
While clamps appear universal, this genuine Goodman OEM clamp is sized to the exact hose diameter and fitting profile used on this furnace, providing consistent clamping force without crushing the tubing. Ill-fitting generic clamps can under-seal or pinch hoses. The OEM part guarantees a proper, durable seal.
Easy (1/5). Power off the furnace, slide the new clamp over the hose, seat the hose fully on the fitting, and tighten or crimp to secure. Verify there is no movement and no leak after restart. A quick 5–10 minute job for any DIYer or technician. Keep spares on hand for routine condensate-system service.
