This is the genuine OEM Goodman A3468601 pressure switch tubing, engineered as the correct-fit draft-sensing hose for the Goodman GMV81155CXBA variable-speed furnace and many related Goodman and Amana 80% AFUE models. This 3/16" inner-diameter tube connects the pressure switch to the inducer housing or collector box, transmitting the pressure signal that verifies proper draft before the furnace fires. Cracked, brittle, or disconnected tubing is one of the most common causes of a furnace that ignites and then shuts down on a pressure-switch fault.

Specifications

Inner Diameter: 3/16 inch
Type: Pressure switch / draft sensing tubing
Material: Heat-resistant silicone hose
Brand: Goodman / Amana OEM
Equipment: Gas furnace (GMV81155 series)

OEM vs. Generic

Generic bulk tubing may not match Goodman's exact durometer or temperature rating, leading to premature hardening and false pressure-switch trips. This genuine OEM hose is cut and rated to Goodman's original specification for reliable, long-term draft sensing.

Installation Difficulty

Easy (DIY-friendly) — Slip the tube onto the barbed fittings; no tools required. Always shut off power and gas before servicing. If unsure, consult a licensed HVAC technician.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman GMV81155 — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman GMV81155 — 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 GMV81155 — 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.
