• This 5140062-38 pressure switch leaves the factory preset for 105 psi cut-in and 135 psi cut-out. In real operation, this means that when tank pressure drops to 105 psi, the switch powers your compressor motor to rebuild tank pressure. The motor stops automatically when the switch reaches the 135 psi cut-out setting. This preset is ideal for 1-6 gallon hand-carry compressors and supports your common pneumatic tools such as brad nailers, finish guns and airbrushes. No need to fiddle with hidden allen screws or unmarked adjustment nuts. When a previous owner lost the installation manual or overtightened something, this factory-preset switch saves you from guessing at correct pressure settings.

• Old pressure switches fail in four ways： → Compressor won't start — the electrical contacts inside the switch become pitted, carbon-coated or physically worn out → Compressor runs but never stops — the switch mechanism sticks open, causing dangerous over-pressure → Motor turns on and off erratically — tank pressure mismatches the switch cut-in and cut-out windows due to failed internal diaphragm → Air leaking from pressure switch body — cracked housing or worn seals inside the switch itself Our 5140062-38 replacement cures all of these problems in one single swap. For safety： always unplug your compressor and drain the tank completely before you remove the old pressure switch.
• ⚠️ Always check thread configuration： This unit uses a 1/4 inch female pipe thread (FPT). If your current pressure switch connects to the tank with 1/8 inch NPT or a different port count, you may need an alternate part.
