Review on 💨 240V Air Compressor Pressure Switch Control Valve with Adjustable Range of 90-120 PSI by Tim Surridge

If you have a Harbor Freight air compressor (like my 2hp 8 gallon Mdl 95386) this is probably the switch you need. I was frustrated with the Harbor Freight parts department after getting the wrong part three times when trying to get a replacement check valve. Their failed attempts caused me to look elsewhere. Importantly, many Harbor Freight Air Compressors use fittings with British Standard Pipe (BSP) threads rather than NPT (American) threads. They are often displayed as "G1/4", "G1/2" or similar. Probably the most important feature of this pressure switch is that it has 1/4" BSP threads, NOT 1/4" NPT. It would be very helpful if the supplier stated that the fittings are BSP threads and not NPT threads. I found this information in the review/questions on this part. This is a major advantage of Harbor Freight air compressors. The product I received is made with reasonable quality for the price. A small adjustment of the print area (for my personal needs) was easy. Initially the limit was about 115psi and the inlet was about 90psi. I can't go wrong with the price.
