fittings and couplings for air compressor

Still waiting for my electrian to hook up my outlet for my air compressor. meantime, still trying to figure out my air compressor fittings. I found this topic , which gave some info.

I purchased a vt6271 horitizontal air compressor from C-H. Trying to figure out what the size of fitting that needs to go into my regulator on my air compressor (it came with a regulator) so I can connect a hose to it. I looked in the manual and it doesn't say anything about the size of the hole on the regulator for a fitting to fit. Are they all a standard size? Is there a way to find out or call the company?

Another question. I want to use a 1/2in air hose for my 3/4 impact wrench. However, my impact wrench has a 3/8 npt fitting. To my understanding, the npt represents the female end on the impact wrench? I can't use a 1/2in fitting, it has to be a 3/8 male end to fit into the impact wrench? So I should by a 1/2 in hose with 3/8 npt ends? Sorry for my stupidness. I'm trying to learn this info.

Thanks for any advice.

your fitting for the regulator is probably 3/8. take a 3/8 hose and see if it will fit. you can use a 3/8 to 1/2 reducer for your gun.
