Goodman A3468601 Pressure Switch Tubing (3/16" ID)

The Goodman A3468601 is genuine OEM 3/16" inside-diameter pressure switch tubing for the AMH81155CXCA furnace and many other Goodman/Amana gas models. This flexible hose carries the vacuum signal from the inducer or vent pickup to the air-proving pressure switch, allowing the switch to confirm proper draft before ignition.

Specifications

Inside diameter: 3/16 inch
Material: heat-resistant flexible tubing
Application: pressure switch / inducer draft-proving line
Fits Goodman & Amana 80% and 90%+ furnaces using 3/16" ID hose
Sold as OEM replacement length

OEM vs. Generic

Cracked, hardened, or collapsed tubing is one of the most common causes of intermittent pressure-switch lockouts. The OEM A3468601 is cut and specified for the correct fit and temperature rating on your furnace. Generic vinyl tubing can soften near the inducer or lose its seal over time; genuine OEM hose keeps the vacuum signal accurate.

Install Difficulty

Very Easy (1/5). Power down the furnace, slide the old tubing off the switch and inducer ports, and press the new hose fully onto each fitting. No tools required in most cases. Inspect that the run is free of kinks and moisture traps for a reliable draft signal.
