The Goodman A3468601 is a genuine 3/16 inch inside-diameter pressure switch tubing designed for the AMH80704BNAB gas furnace and other compatible Goodman and Amana models. This small but critical hose carries the negative pressure signal from the inducer draft port to the pressure switch, allowing the switch to confirm proper venting before the furnace ignites. Cracked, hardened, or disconnected tubing is one of the most common causes of a furnace that clicks but will not light.

Specifications

Inside diameter: 3/16 inch (0.1875")
Application: draft/pressure switch sensing line
Material: heat-resistant silicone hose
Fits: Goodman & Amana furnaces including AMH80704BNAB
Part number: A3468601

OEM vs. Generic

This is the factory-spec OEM tubing engineered to survive years of furnace heat cycling without hardening or collapsing. Bulk generic vinyl tubing may fit dimensionally but often stiffens and cracks under sustained heat, leading to intermittent pressure-switch faults. For a reliable long-term repair, OEM is the safe choice at a nearly identical price.

Installation Difficulty

Easy (1/5). Power down the furnace, pull the old hose off the inducer port and switch nipple, and slide the new tubing on with a firm push. No tools required. Typical replacement takes under five minutes.
