ID Pressure Switch Tubing\u003c\/h2\u003e\u003cp\u003eThe Goodman A3468601 is genuine OEM 3\/16 inch inside-diameter pressure switch tubing, cut and specified as a direct-fit replacement for Goodman GMNT040-3 furnaces and compatible Goodman\/Amana models. This small hose connects the inducer or collector box to the pressure switch, letting the switch confirm proper draft before the gas valve opens. Over time the tubing hardens, cracks, or clogs with condensate, causing pressure-switch lockout faults and no-heat calls. Replacing it is one of the cheapest, fastest furnace repairs you can make.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: A3468601\u003c\/li\u003e\n\u003cli\u003eInside diameter: 3\/16 in.\u003c\/li\u003e\n\u003cli\u003eType: Pressure switch \/ draft sensing tubing\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMNT040-3 and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eMaterial: Heat-resistant flexible hose\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis genuine Goodman tubing is the correct diameter and heat rating for the pressure-switch circuit, so it seals tightly on both barbs and withstands flue-area temperatures. Generic hose that is slightly off-size can slip, leak, or soften near the inducer, re-creating the exact fault you are trying to fix. OEM is inexpensive insurance for a reliable seal.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (1 of 5).\u003c\/strong\u003e Cut power, pull the old tubing off the pressure switch and inducer barbs, and push the new hose fully onto both fittings, matching the original routing.
