Goodman A3468601 3/16" ID Pressure Switch Tubing

The A3468601 is genuine OEM Goodman pressure-switch tubing with a 3/16-inch inside diameter. This heat-resistant hose carries the vacuum signal from the inducer draft port to the furnace pressure switch, allowing the switch to confirm proper venting before ignition. It is an exact-fit replacement for the Goodman DDS80904BXA gas furnace and compatible Goodman/Amana models. Cracked, brittle, or clogged tubing is a leading cause of pressure-switch lockout and no-heat calls.

Specifications

Inside diameter: 3/16 in.
Function: Draft/vacuum sensing line to pressure switch
Material: High-temperature flexible tubing
Fits: Goodman DDS80904BXA and compatible furnaces
OEM Part Number: A3468601

OEM vs. Generic

Our OEM Goodman tubing is rated for the high underhood temperatures and vacuum requirements of the sensing circuit, ensuring a leak-free signal and long service life. A Generic equivalent 3/16" ID high-temp hose provides an economical fix for quick repairs. Both restore reliable switch operation; OEM is preferred for guaranteed temperature rating.

Installation Difficulty

Easy (1/5). Power down the furnace, slip the old tube off both barbed ports, cut the new tubing to matching length, and press it firmly onto each fitting. Verify no kinks or moisture traps. No tools beyond a utility knife required.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman DDS80904BXA — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman DDS80904BXA — 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 DDS80904BXA — 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.
