The Goodman A3468601 is genuine OEM 3/16-inch ID pressure switch tubing for the Goodman GMTH115-5 furnace and related models. This flexible, heat-resistant hose connects the pressure switch to the inducer draft port, allowing the switch to sense proper venting airflow before the burners fire. Cracked, hardened, or disconnected tubing is a common cause of pressure-switch lockout and no-heat calls.

Inside Diameter: 3/16 inch
Type: Pressure switch / inducer sensing tubing
Material: Heat-resistant flexible hose

OEM vs. Generic

The OEM tubing is rated for the temperatures and vibration inside the burner compartment and holds its seal over time. Cheap generic vinyl hose can soften, kink, or blow off the barb, creating false pressure faults. For reliable draft-proving, use the OEM-spec hose.

Installation Difficulty

Very Easy (1/5). Slip the old tube off the pressure switch and inducer barbs and press the new one on. No tools needed. Ensure a snug, kink-free routing and confirm both ends are fully seated. Shut off power and gas before servicing.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman GMTH115-5 — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman GMTH115-5 — 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 GMTH115-5 — 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.
