The Goodman A3468601 Pressure Switch Tubing is the OEM 3/16" inside-diameter hose that connects the inducer/collector box to the pressure switch on the ADV81155CXBB furnace and compatible Goodman/Amana models. Over years of heat cycling, this tubing hardens, cracks, or slips off its barb — causing intermittent pressure-switch faults and lockouts that mimic a failed switch.

Part number: A3468601
Inside diameter: 3/16 inch
Type: High-temp silicone pressure-switch hose
Fits: Goodman ADV81155CXBB and compatible furnaces
Function: Carries negative pressure signal to the switch

OEM vs. Generic: The OEM Goodman hose is cut to the correct length and rated for furnace vestibule temperatures, so it seats fully on both barbs without kinking. Generic silicone tubing is an economical alternative sold by the foot but must be trimmed to fit and matched to the 3/16" ID.

Install difficulty: Very easy — under 10 minutes. Power down the furnace, pull the old hose off both fittings, and press the new tubing fully onto each barb. Confirm there are no sharp bends that could restrict the pressure signal. No tools required.
