This small silicone hose carries the vacuum signal from the inducer\/collector box to the pressure switch, confirming proper draft before the furnace allows ignition. Cracked, hardened, or plugged tubing is a common cause of a furnace that will not light or that locks out on a pressure-switch fault.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Pressure switch signal tubing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner diameter:\u003c\/strong\u003e 3\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM part number:\u003c\/strong\u003e A3468601\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits model:\u003c\/strong\u003e AMS80905CNA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e High-temp silicone rubber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Draft\/vacuum sensing line\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM A3468601 is cut and formulated to hold a stable vacuum signal at furnace flue temperatures. Generic tubing may be the wrong durometer or wall thickness, allowing micro-leaks that produce intermittent, hard-to-diagnose pressure-switch lockouts.

Power down the furnace, pull the old tube off both barbed fittings, and press the new tube fully onto each port with no kinks or low spots that could trap condensate. No tools required.
