Product Details
H439336 - Pressure Switch, 155 PSI
Brand: Husky
Part Number: H439336 - Compatible replacement parts for original Husky models

This item is contained in the following kits:


155 PSI cut-off, w/ 90 degree quick-lock unloader valve, 4-port manifold, on/off switch.

Essentially the “brain” of the air compressor, the pressure switch senses the pressure in the tank and controls when the unit shuts on and off. All switches are preset for specific cut-on and cut-out pressures at the factory, so be sure to order the exact OEM part number your manual calls for, or make sure the specs are identical to your original if you do not have a part number to order by. The major brands are Furnas (Hubbell), SquareD, Condor and Huanli. Most have either a single port or four-port manifold to attach a safety relief valve, pressure gauge or an air regulator. Replace this if the unit doesn’t cut on and off at the specified pressures for your unit, if it leaks or if the copper contacts inside are corroded or burnt.

Extra Details

If the 90-degree unloader valve leaks (where the 1/4" bleeder line installs) constantly after the compressor shuts off, you have a defective tank Check Valve; your pressure switch is okay.
