The Goodman A3468601 Pressure Switch Tubing is a genuine OEM 3/16-inch ID hose for the AMH80604BNBB gas furnace. This small silicone/rubber tube connects the pressure switch to the inducer housing or collector box, transmitting the negative-pressure signal that proves proper venting before the burners fire. Cracked, brittle, or clogged tubing causes pressure-switch faults and ignition lockouts.

OEM vs. Generic

OEM A3468601 tubing is rated for the temperatures and flexibility your furnace requires, with the correct 3/16" bore for an accurate pressure reading. Generic tubing may harden or size incorrectly, causing false pressure-switch trips. OEM ensures reliable draft sensing.

Installation Difficulty

Easy — A quick DIY fix. Power down the furnace, pull the old tube off both barbed fittings, and press the new length firmly onto each nipple. Verify a snug, kink-free routing before restoring power.
