This small tube transmits the negative pressure signal that proves the inducer is moving combustion air before the furnace allows ignition. Cracked, brittle, or condensate-clogged tubing causes nuisance pressure-switch lockouts and no-heat calls — fresh OEM hose restores a clean, accurate draft signal.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eInside diameter: 3\/16\"\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: A3468601\u003c\/li\u003e\n\u003cli\u003eFits: Goodman ADS81155CXA gas furnace\u003c\/li\u003e\n\u003cli\u003eMaterial: Heat- and condensate-resistant silicone\/rubber tubing\u003c\/li\u003e\n\u003cli\u003eFunction: Inducer-to-pressure-switch sensing line\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e hose uses the correct ID and a high-temperature compound that resists hardening near the inducer.
