This flexible tube connects the furnace pressure switch to the inducer assembly or collector box, allowing the switch to accurately sense negative pressure and confirm proper venting before ignition. Cracked, brittle, or disconnected tubing is one of the most common causes of a furnace that ignites and immediately shuts down on a pressure fault.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter:\u003c\/strong\u003e 3\/16\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Pressure switch sensing line\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit:\u003c\/strong\u003e Direct OEM replacement for DDS81155CXA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Heat-resistant flexible tubing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman \/ Amana genuine OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine Goodman A3468601 tubing is manufactured to the exact wall thickness and temperature rating specified for your furnace, ensuring a leak-free seal at both the switch port and the inducer fitting. Universal generic tubing may match the diameter but can soften, kink, or leak over time — leading to nuisance lockouts and repeat service calls. For a critical safety-sensing component, OEM tubing delivers reliable, code-compliant performance.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Easy (1\/5)\u003c\/h3\u003e\u003cp\u003eReplacement takes only a few minutes with no special tools.

Always verify a snug, kink-free run before restoring power.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058012668275,"sku":"GOODMAN-9455","price":6.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-3-16-id-pressure-switch-tubing-for-dds81155cxa-a3468601","provider":"National HVAC Parts","version":"1.0","type":"link"}
