Intentional air leak International DT530

Hello everyone, I was doing some basic maintenance on my engine and I noticed that there is this very small air leak in the middle of this fitting on the air compressor. It is the fitting that attaches to the air pressure sensor I do believe. The air seems to be emanating from the middle of the fitting itself. I was just curious if this fitting had an intentional small hole in it to allow moisture to escape or some other possibility. I wasn’t sure. If not, I can replace the fitting and stop the leak, but the leak is very small as it is.

Air brake systems already have water separators and or air dryers... I would reseal or replace that fitting as it clearly is an air leak and there should be NO air leaks in a properly working air brake system.

Very well. Thanks for the reply, I will replace that fitting asap.
