This small-diameter hose carries the pressure signal between the inducer\/collector box and the furnace's pressure (draft) switch. A clean, flexible, correctly-sized tube is essential for accurate draft sensing — if the tubing cracks, kinks, or fills with condensate, the pressure switch may fail to close and the furnace will lock out before ignition.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Pressure switch signal tubing\u003c\/li\u003e\n\u003cli\u003eInside diameter: 3\/16\"\u003c\/li\u003e\n\u003cli\u003eMaterial: Flexible high-temperature hose\u003c\/li\u003e\n\u003cli\u003eFunction: Connects inducer\/collector to pressure switch\u003c\/li\u003e\n\u003cli\u003eBrand fit: Goodman \u0026amp; Amana furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part #: A3468601\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOEM A3468601 tubing is rated for furnace heat and holds its 3\/16\" bore without collapsing, so the pressure signal reaches the switch reliably. Generic hardware-store tubing can soften, kink, or use a slightly off ID that leaks at the barbs, causing intermittent no-heat lockouts. For a trouble-free repair, use the factory-spec hose.\u003c\/p\u003e\u003ch3\u003eInstallation\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eDifficulty: Easy.\u003c\/strong\u003e This is one of the simplest furnace repairs — most homeowners can do it in under 10 minutes. Power down the furnace, pull the old tube off both barb fittings, and press the new tubing fully onto each barb, routing it with no low spots where condensate can pool. Trim to length if needed. If the furnace still trips on pressure switch after replacement, inspect the inducer and vent for blockage.\u003c\/p\u003e\u003cp\u003eQuestions about routing or length?
