Actually it's a truck oil cooler (picture is wrong ... see the size specs for actual size)
It has 3/4" NPT female fittings ... one of the reasons I used that line of cooler, with the NPT threads I could adapt anything I wanted. I found the pressure specs and the working pressure limit was 300 psi. They are commonly used by people building compressor after coolers. I'd make sure you have 18" or so of copper line between the compressor head outlet and the inlet of the cooler. Air coming out of the compressor head is VERY hot, 18" or so of copper will reduce the temps to a more reasonable level before it gets to the cooler.
