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.
