The Goodman A3468601 Pressure Switch Tubing is genuine OEM 3/16-inch inside-diameter hose for the AMH80803BXBA gas furnace and compatible Goodman/Amana models. This small silicone/rubber tube connects the draft-inducer pressure tap to the pressure switch, letting the switch sense negative pressure and confirm proper venting before the burners ignite. Cracked, kinked, or condensate-blocked tubing is one of the most common causes of pressure-switch lockouts and intermittent no-heat codes.

Specifications

OEM Part Number: A3468601
Inside Diameter: 3/16 inch
Application: Inducer-to-pressure-switch sensing line
Compatible Model: AMH80803BXBA
Material: High-temp flexible tubing

OEM vs. Generic

The OEM A3468601 tubing uses the correct ID and heat-rated material to seat tightly on the switch and inducer ports without slipping or hardening. Hardware-store hose often has the wrong wall thickness, cracks near heat, or leaks at the fittings — defeating the pressure switch's safety function.

Installation Difficulty

Easy (1/5) — Pull the old tube off both barbs, route the new tube along the same path, and press it firmly onto each port. Under 5 minutes; confirm no kinks and no trapped condensate.
