This flexible high-temperature silicone hose carries the reference pressure signal between the inducer housing and the pressure switch, allowing the control board to confirm safe venting before the burners fire. Cracked, brittle, or collapsed tubing is one of the most common causes of nuisance lockouts and \"open pressure switch\" fault codes.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eInner diameter: 3\/16 in.\u003c\/li\u003e\n\u003cli\u003eMaterial: high-temperature silicone rubber\u003c\/li\u003e\n\u003cli\u003eApplication: draft\/pressure switch signal line\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMT140-5A and compatible Goodman \u0026amp; Amana 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\u003eThe genuine Goodman A3468601 is molded from furnace-rated silicone that resists heat aging and will not harden or split like generic vinyl tubing. Aftermarket hose is cheaper up front but often shrinks or cracks within a season, forcing a repeat repair. For a reliable, code-compliant fix, the OEM hose is the right call.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy\u003c\/strong\u003e — a slip-on repair most homeowners can complete in minutes with power off.
