The Goodman A3468601 Pressure Switch Tubing is a genuine OEM 3/16" ID hose designed for the Goodman GDS81155CXA gas furnace. This small but critical tube connects the inducer/collector box to the pressure switch, allowing the switch to sense proper draft before the furnace permits ignition. Cracked, brittle, or clogged tubing is one of the most common causes of a furnace that locks out on a pressure-switch fault and refuses to fire.

Made from heat- and moisture-resistant material to Goodman's specification, this tubing maintains a leak-free vacuum signal so the pressure switch reads draft accurately. The exact 3/16" inside diameter ensures a snug, secure fit over the factory barbed fittings without kinking.

OEM Part Number: A3468601
Inside Diameter: 3/16"
Compatible Model: Goodman GDS81155CXA
Category: Pressure Switch
Equipment Type: Gas Furnace
Function: Draft-signal line to pressure switch

OEM vs. Generic

OEM A3468601 guarantees the correct 3/16" ID and heat rating for a reliable vacuum seal. Generic tubing may use a slightly different diameter or lower temperature rating, risking air leaks, false pressure-switch trips, and premature failure. OEM ensures safe, consistent operation.

Installation Difficulty

Rating: Very Easy (1/5). Slide the old hose off the barbed fittings and press the new tubing on — under 10 minutes, no tools required. Confirm both ends are fully seated and free of kinks. A technician should verify pressure-switch operation if lockouts persist.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman GDS81155CXA — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman GDS81155CXA — 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 GDS81155CXA — 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.
