The Goodman A3468601 is genuine OEM 3/16 inch inside-diameter pressure switch tubing for the WGGE4560A140MAB furnace. This small but essential hose connects the draft-inducer pressure tap to the air-proving pressure switch. Hardened, cracked, or clogged tubing is a frequent and often-overlooked cause of furnace pressure-switch lockouts and no-heat calls. Replacing this inexpensive part can resolve intermittent ignition faults.
While tubing seems universal, the OEM Goodman hose is rated for furnace flue-area temperatures and provides an exact ID for a leak-free press fit on the switch and inducer barbs. Cheap PVC tubing can harden, collapse, or leak, causing false pressure faults. The genuine part is inexpensive insurance.
Very Easy — Pull the old hose off both barbs and press the new one on, matching the original routing so it doesn't kink or trap condensate. No tools required. A quick, low-cost fix any homeowner can handle.
In stock and ready to ship. A smart part to keep on hand during furnace maintenance.
