The OEM Goodman A3468601 pressure switch tubing is a direct-fit replacement for GMT140-5 gas furnaces. This 3/16-inch inside-diameter hose connects the inducer or collector box to the pressure switch, letting the switch sense proper draft before the furnace fires. Cracked, hardened, or disconnected tubing is a common cause of pressure-switch lockouts and no-heat calls, and this genuine-fit replacement restores accurate sensing.

Specifications

Inside diameter: 3/16 inch
Function: Pressure switch / draft sensing line
Material: Heat-resistant flexible tubing
Fits: Goodman GMT140-5 furnace
OEM Part Number: A3468601

OEM vs. Generic

The genuine Goodman tubing is sized and rated for the furnace's operating temperature and vacuum, so it stays supple and leak-free through repeated heating cycles. Bulk generic hose can be too stiff or the wrong diameter, causing loose port connections and false pressure readings. The correct OEM ID ensures a snug, reliable seal on both nipples.

Install Difficulty

Very Easy (1/5) — Turn off power, pull the old tube off both ports, and press the new tubing fully onto each barbed fitting. A 5-minute repair with no tools. Confirm the routing avoids hot surfaces and has no kinks.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman GMT140-5 — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman GMT140-5 — 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 GMT140-5 — 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.
