Installation was straightforward. However, I have yet to achieve more than 95 psi with the compressor running for 10-15 minutes from an empty tank start, whereas prior to my old pressure switch failing, I was able to get 120psi within 10 minutes from an empty tank start. There are some set screws adjustments that I have not had time to adjust yet. Also, the compressor has not yet reached a "self-cut off" pressure yet either. After it hovers at 95psi for several minutes, I just manually cut it off because of the noise in the garage. ## 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 | #21,755 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #8 in Industrial Pressure Regulators | | Brand | QWORK | | Brand Name | QWORK | | Customer Reviews | 4.2 out of 5 stars 1,461 Reviews | | Included Components | No included components | | Item Weight | 671 g | | Manufacturer | QWORK | | Manufacturer Part Number | WD3785 | | Material Type | Acrylonitrile Butadiene Styrene | | Maximum Pressure | 120 psi | | Model Name | WD3785 | | Model Number | WD3785 | | Number of Items | 1 | | Recommended Uses For Product | Pressure Control in Air Compressor Systems | | Special Feature | Precision Measurement, Portable | | Style | Portable | | Unit Count | 1 Count | | Voltage | 240 volts | ## Product Details - **Brand:** QWORK - **Included Components:** No included components - **Recommended Uses For Product:** Pressure Control in Air Compressor Systems - **Special Feature:** Precision Measurement, Portable - **Voltage:** 240 volts ## Images ![Air Compressor Pressure Switch for Pneumatic Tools, 90–120PSI Adjustable Controller - Image 1](https://m.media-amazon.com/images/I/71Bnr+YZ8QL.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 ### ⭐⭐⭐⭐⭐ Air compressor pressure switch *by J***S on August 27, 2026* Air compressor pressure switch works great ### ⭐⭐⭐⭐⭐ It seems to be a good product for the price. *by A***R on September 14, 2026* Delivery was uneventful.
