This flexible silicone hose connects the pressure switch to the inducer draft assembly, carrying the negative pressure signal that verifies proper venting before the burners are allowed to ignite. Over years of thermal cycling the factory tubing can harden, crack, or collapse, causing nuisance lockouts and \"pressure switch open\" fault codes. Replacing it with the correct OEM length and diameter restores reliable, code-compliant operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eInner diameter: 3\/16 inch\u003c\/li\u003e\n\u003cli\u003eMaterial: high-temperature silicone hose\u003c\/li\u003e\n\u003cli\u003eApplication: inducer-to-pressure-switch sensing line\u003c\/li\u003e\n\u003cli\u003eFit: Goodman\/Amana AMH80905CNAC and compatible 80% furnaces\u003c\/li\u003e\n\u003cli\u003eOEM part number: A3468601\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGeneric bulk tubing may seem interchangeable, but incorrect ID or wall thickness leads to air leaks, false pressure readings, and repeat failures.
