The genuine Goodman A3468601 is a 3/16" inside-diameter pressure switch tubing designed for the Goodman DDS81155CXA gas furnace and other compatible Goodman and Amana models. 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.

Inside Diameter: 3/16"
Function: Pressure switch sensing line
Fit: Direct OEM replacement for DDS81155CXA
Material: Heat-resistant flexible tubing
Brand: Goodman / Amana genuine OEM

OEM vs. Generic

The 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.

Installation Difficulty: Easy (1/5)

Replacement takes only a few minutes with no special tools. Power down the furnace, note the tubing routing, slide the old tube off both barbed fittings, and press the new tube firmly into place. Always verify a snug, kink-free run before restoring power.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman DDS81155CXA — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman DDS81155CXA — A3468601. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.

How do I replace the pressure switch tubing on my Goodman DDS81155CXA — A3468601?

Difficulty: Medium (20–30 min)
Step 1: Turn off power. Step 2: Locate pressure switch near draft inducer. Step 3: Note tubing orientation. Step 4: Disconnect tubing and wires. Step 5: Remove screw, install new switch. Step 6: Reconnect tubing and wires, restore power.

My furnace shows a pressure switch error. What do I replace?

Furnace LED showing pressure switch error = switch not detecting draft inducer airflow. Try first: clear the rubber tubing to the switch (often clogged with condensation). If problem persists, replace the pressure switch.

Is this pressure switch tubing compatible with Bryant or Payne too?

Many Goodman parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

Should I use OEM or aftermarket for my Goodman pressure switch tubing?

OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
