This flexible hose connects the inducer draft port to the pressure switch, allowing the furnace to verify proper venting before the gas valve opens. Cracked, brittle, kinked, or clogged tubing is one of the most common — and cheapest — causes of a furnace that ignites then shuts down on a pressure-switch fault.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eInside diameter: 3\/16 in.\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: A3468601\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMTH045-3A and cross-compatible furnace models\u003c\/li\u003e\n\u003cli\u003eApplication: Draft \/ pressure switch sensing line\u003c\/li\u003e\n\u003cli\u003eMaterial: High-temperature silicone hose, sold to factory length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGenuine OEM silicone tubing is rated for the furnace's heat and condensate exposure and holds its shape without collapsing under vacuum.

Power down the furnace, slip the old hose off the inducer barb and pressure-switch port, and press the new tubing fully onto each fitting. Route it with a downward slope where possible to shed condensate and avoid traps. No tools required beyond checking for a snug fit.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058165530995,"sku":"GOODMAN-12527","price":2.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-3-16-in-id-pressure-switch-tubing-for-gmth045-3a-a3468601","provider":"National HVAC Parts","version":"1.0","type":"link"}
