The Goodman A3468601 is factory-original 3/16" inside-diameter tubing that connects the pressure switch to the inducer/collector box on the AMH81405DNAA gas furnace. This small hose lets the pressure switch sense proper venting/draft before the furnace allows ignition. Cracked, hardened, kinked, or clogged tubing is a common cause of pressure-switch lockout faults and no-heat calls, and is one of the least expensive parts to replace.
The genuine A3468601 uses the correct 3/16" ID, wall thickness, and heat-resistant material to seal tightly on the factory ports without slipping or collapsing. Generic tubing may have a mismatched ID or lower temperature rating, leading to leaks, false pressure readings, and repeat failures. At this price, OEM is the obvious pick.
Easy (DIY-friendly). Power off the furnace, pull the old tubing from both ports, and press the new tube fully onto each fitting — no tools required. Confirm a snug, leak-free connection before restoring power.
