The Goodman A3468601 Pressure Switch Tubing is a genuine OEM 3/16-inch inside-diameter hose for the AMS81155CNA furnace and other compatible Goodman and Amana gas furnaces. This flexible high-temperature tube connects the inducer/pressure tap to the draft pressure switch, carrying the negative-pressure signal that proves proper venting before the burners are allowed to fire. Cracked, brittle, or clogged tubing is a common cause of pressure-switch faults and no-heat lockouts.

Specifications

Part number: A3468601
Type: Pressure switch sensing tubing
Inside diameter: 3/16 inch
Material: High-temperature silicone
Function: Transmits draft-pressure signal to the pressure switch
Fits: Goodman / Amana AMS81155CNA and compatible furnaces

OEM vs. Generic

The genuine OEM Goodman silicone tubing is rated for the elevated temperatures near the inducer and resists hardening over time. Generic vinyl tubing may soften, collapse, or crack, producing intermittent pressure-switch trips. OEM tubing ensures reliable pressure sensing and long service life.

Installation Difficulty

Very Easy (1/5). Slip the old tube off the pressure-tap and switch ports and press the new length on, routing it clear of hot surfaces. Confirm the pressure switch closes on a call for heat after replacement. No tools required.
