About this item

  • 🔧 Controls Compressor On/Off Based on Tank Pressure: Designed for the Oasis XD3000 and XD4000 air compressors, this switch threads into your air tank and manages when the compressor turns on and off.
  • ⚙️ Adjustable On/Off Range from 100–250 PSI: Built-in set screw lets you fine-tune compressor cycling with adjustable cut-on and cut-off pressures in 30–40 PSI increments. Ships pre-set at 110 PSI on / 150 PSI off.
  • 🔩 1/4" NPT Male Thread for Easy Tank Mounting: Installs directly into your air tank using a standard 1/4" NPT male fitting. No special adapters required.
  • ✅ Reliable Control for High-Performance Air Systems: Maintains safe, consistent pressure levels in onboard air systems, helping prevent over-pressurization and unnecessary compressor cycling.


The Oasis Adjustable Pressure Switch is built to give you precise control over your Oasis XD3000 or XD4000 compressors. Installed directly into your air tank, it regulates when the compressor turns on and off based on system pressure. It comes pre-set to activate at 110 PSI and shut off at 150 PSI, but includes an adjustment screw that lets you fine-tune the range from 100 to 250 PSI in 30–40 PSI increments. This flexibility makes it ideal for dialing in custom pressure settings across a wide range of onboard air applications. The switch uses a standard 1/4" NPT male thread, making installation simple and compatible with most air tanks. Whether you're powering train horns, air tools, suspension systems, or other pneumatic gear, this switch ensures reliable compressor cycling and long-term system performance.
