This flexible hose carries the negative-pressure (draft) signal from the inducer housing or vent to the pressure switch, which proves proper venting before allowing ignition. Cracked, brittle, or clogged tubing is a leading cause of a furnace that ignites and immediately shuts off or throws a pressure-switch fault.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: A3468601\u003c\/li\u003e\n\u003cli\u003eInside Diameter: 3\/16 inch\u003c\/li\u003e\n\u003cli\u003eType: Flexible pressure\/draft signal tubing (hose)\u003c\/li\u003e\n\u003cli\u003eFunction: Connects inducer\/vent port to the pressure switch\u003c\/li\u003e\n\u003cli\u003eFits: Goodman DHS80453AXA and select Goodman\/Amana furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGenuine Goodman tubing is sized and rated for furnace flue-gas heat and holds a stable seal on the switch and inducer ports so the pressure signal reads true.
