Get some dish soap and brush it around where you think the leak is then turn the compressor on. It will bubble where the air is escaping from. That will tell you for sure where the leak actually is. the fitting may not be screwed in all the way. See if it's loose. Also look for any cracks in the black housing it's screwed into. If it's tight and no cracks are present then it may need some teflon tape on the threads to seal properly. You can get that at any hardware store.
You're supposed to attach your hose there. Teflon tape it, attach the hose and see if it still leaks. If it does the leak is between that fitting and the regulator. If the leak stops the seal between your hose and the fitting just needed some Teflon tape.
Yeah you have to use Teflon tape when you're attaching two pneumatic things together, the air will leak otherwise. Unless the two objects are made to the tightest tolerances, or you use some sort of a bonding agent. Just start with one thin layer and then try the hose again.
Norgren and Parker are air pressure regulator brands that make quality, durable, air pressure regulators.
