This flexible hose connects the furnace's pressure switch to the inducer draft assembly, allowing the switch to sense proper venting airflow before the burners are allowed to fire. Cracked, brittle, or clogged tubing is a frequent cause of pressure-switch lockouts and no-heat conditions, so replacing worn tubing with the correct OEM hose is an inexpensive, high-impact repair.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eInside diameter: 3\/16 inch (ID)\u003c\/li\u003e\n\u003cli\u003eType: Pressure switch \/ draft-sensing tubing\u003c\/li\u003e\n\u003cli\u003eMaterial: Heat-resistant flexible hose\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman OEM\u003c\/li\u003e\n\u003cli\u003eFits: GMTH070-4A and compatible Goodman furnaces\u003c\/li\u003e\n\u003cli\u003ePart number: A3468601\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM A3468601 uses the correct inside diameter and heat-rated material to maintain an airtight seal on the pressure switch and inducer ports. Generic tubing may be available cheaper but can vary in wall thickness and temperature rating, risking a poor seal or premature failure near hot components. For dependable sensing and long life, the OEM hose is preferred.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eVery Easy (~5–10 minutes).\u003c\/strong\u003e Turn off power at the breaker. Pull the old tubing off the pressure switch and inducer barbs, then press the new tubing fully onto both ports, matching the original routing and avoiding kinks or contact with hot surfaces. Restore power and verify the furnace completes its ignition sequence.
