Application Air compressor pressure switch Control valve is designed to control and adjust air compressor pressure and better for high efficiency working. Review: Great product for California Air Tools - Working great! Review: Worked in a pinch - So far good. Purchased this for an old 20gal 125psi max compressor that had a faulty pressure switch and no longer switched off when it reached the desired pressure. Doesn't come with any instructions, but does have a wiring diagram on the inside of the cap. Ended up not using the smaller air valve, hose connector and pressure relief valve as they were of much lower quality compared to what I already had. Between the new part and my old part, I had enough parts to make the repair. This kit doesn't come with any thread tape, so have that purchased ahead of time and ready, you will need it on ALL threads. Doing this, I had ZERO leaks. ## Features - PRECISE SWITCH RANGE: Automatically activates at 90 PSI and stops at 120 PSI for stable compressor control. - STANDARD THREAD TYPE: Built with G1/4 BSP joints, not compatible with NPT-threaded compressors. - STURDY METAL HOUSING: Reinforced ABS cover with iron fittings provides corrosion resistance and long operation life. - EASY DEVICE CONNECTION: Pre-assembled dual gauges and regulator ready for quick tool installation. - FOR MULTIPLE USES: Perfect for workshops, garages, and pneumatic equipment setups up to 175 PSI. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08FBCDNR5 | | Additional Features | Precision Measurement, Portable | | Best Sellers Rank | #10,680 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #3 in Industrial Pressure Regulators | | Brand | QWORK | | Brand Name | QWORK | | Customer Reviews | 4.2 out of 5 stars 1,336 Reviews | | Item Weight | 671 Grams | | Manufacturer | QWORK | | Manufacturer Part Number | WD3785 | | Material Type | Acrylonitrile Butadiene Styrene | | Maximum Pressure | 120 Pound per Square Inch | | Model Name | WD3785 | | Model Number | WD3785 | | Power Source | Corded Electric | | Recommended Uses For Product | Pressure Control in Air Compressor Systems | | Special Feature | Precision Measurement, Portable | | Style | Portable | | Unit Count | 1.0 Count | | Voltage | 240 Volts | ## Product Details - **Brand:** QWORK - **Voltage:** 240 Volts - **Recommended Uses For Product:** Pressure Control in Air Compressor Systems - **Power Source:** Corded Electric - **Special Feature:** Precision Measurement, Portable ## Images ![QWORK Air Compressor Pressure Switch for Pneumatic Tools, 90–120PSI Adjustable Controller - Image 1](https://m.media-amazon.com/images/I/71Bnr+YZ8QL.jpg) ![QWORK Air Compressor Pressure Switch for Pneumatic Tools, 90–120PSI Adjustable Controller - Image 2](https://m.media-amazon.com/images/I/61VLk98FfmL.jpg) ## Questions & Answers **Q: It turn on fine but it wont shut off on its own like its supposed to do when reaching 120psi,I have to turn off on the on switch which its not normal?** A: Does the compressor continue to run until the overpressure valve activate? Or are you shutting it off when you see 120 on the gage? I have not open mine because it shuts off within + or- 5 PSI of the advertise shut off pressure. Otherwise open the case and adjust the spring tension on the relay to archive the desired on -off range **Q: On this pressure switch does it come with short pipe that screws into the switch as well as the Tank. Also what size is it for 1/2 inch** A: No what you see is what you get **Q: Will it work on 120vac 20 amp** A: Sorry, it won't. **Q: I have a dewalt CAP 1560 will it work?** A: negative ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product for California Air Tools *by C***K on April 13, 2026* Working great! ### ⭐⭐⭐⭐⭐ Worked in a pinch *by K***N on December 29, 2025* So far good.
