The Goodman A3468601 is genuine OEM 3/16-inch ID pressure switch tubing for the GMTH070-4A gas furnace and compatible Goodman/Amana models. This flexible hose connects the furnace's pressure switch to the inducer draft assembly, allowing the switch to sense proper venting airflow before the burners are allowed to fire. Cracked, brittle, or clogged tubing is a frequent cause of pressure-switch lockouts and no-heat conditions, so replacing worn tubing with the correct OEM hose is an inexpensive, high-impact repair.

Specifications

Inside diameter: 3/16 inch (ID)
Type: Pressure switch / draft-sensing tubing
Material: Heat-resistant flexible hose
Brand: Goodman OEM
Fits: GMTH070-4A and compatible Goodman furnaces
Part number: A3468601

OEM vs. Generic

The OEM A3468601 uses the correct inside diameter and heat-rated material to maintain an airtight seal on the pressure switch and inducer ports. Generic tubing may be available cheaper but can vary in wall thickness and temperature rating, risking a poor seal or premature failure near hot components. For dependable sensing and long life, the OEM hose is preferred.

Installation Difficulty

Very Easy (~5–10 minutes). Turn off power at the breaker. Pull the old tubing off the pressure switch and inducer barbs, then press the new tubing fully onto both ports, matching the original routing and avoiding kinks or contact with hot surfaces. Restore power and verify the furnace completes its ignition sequence. Consult a licensed HVAC technician if needed.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman GMTH070-4A — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman GMTH070-4A — 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 GMTH070-4A — 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.
