This FS6733-1474 air pressure switch is a direct replacement for Tridelta Trane furnaces – compatible with models like FCAA, FCAB, FUAA, TDE, TUE, and TUJ series (check the full list to match yours).

It's rated at 0.50 inches w/c and has two wiring terminals and one hose port.

This little switch is a safety device that makes sure your inducer motor is spinning at the right RPM and creating proper vacuum so your furnace vents safely.

It automatically controls your system based on preset pressure thresholds, which helps with energy efficiency and protects your equipment.

Built with corrosion-resistant housing and heavy-duty internals, so it holds up in high-pressure environments.

Easy to install with standard fittings and clear labeling.

Good for residential HVAC or light commercial setups.
