After months of research and videos I decided on the after cooler for the 5-7.5 hp compressors. NOT a transmission coolers. pay attention folks two different functions and operating parameter designs.
The necessary fittings to reduce from 3/4 to 1/2 and the 90* fittings saved me a lot of trips looking for all the parts.
This is one of the better one stop shops for DIY folks needing air compressor parts and help.
Not a welder so am stuck figuring out how to wall mount the after-cooler but at least it will be on hand.
I will be a repeat customer for sure.

Brand new 95-125 PSI air compressor pressure switch or known as a pressure control valve. This switch has four ports on the bottom, one for air inlet hook up and the other three ports are usually used for a relief valve, gauges, or extra air outlets. These four ports are all 1/4" female NPT. This switch is also equipped with an on and off lever and an elbow style unloader valve on the side, which is 1/4" compression, if the unloader is not needed it does not need to be hooked up.
