The Goodman A3468601 Pressure Switch Tubing is a genuine OEM 3/16" inside-diameter hose that connects the furnace pressure switch to the inducer draft port on the AMH80453ANAC gas furnace. This tubing carries the negative-pressure signal the switch needs to confirm proper venting before the burners light. Cracked, brittle, or clogged tubing is a common cause of furnaces that lock out on a pressure-switch fault.

Specifications

Part type: Pressure switch signal tubing
Inside diameter: 3/16 in.
OEM part number: A3468601
Fits model: AMH80453ANAC (80% gas furnace)
Brand: Goodman / Amana
Material: Heat-resistant silicone / rubber hose

OEM vs. Generic

The OEM A3468601 tubing is rated for the temperatures and vacuum levels inside the furnace vestibule and matches the original routing length. Generic hardware-store hose can soften, kink, or split near hot surfaces, leading to intermittent pressure-switch trips. The factory part restores reliable operation.

Installation Difficulty

Very easy (1/5). Slip the old hose off the switch and inducer barbs and press the new tubing on in its place. No tools required beyond disconnecting power to the furnace first. Route the hose away from hot metal and confirm the burners light and stay lit after replacement.
