What is the difference between automotive and industrial air fittings....these indicate they are M fittings...exactly what are M fittings...

1/4" type V HVLP High Volume Low Pleasure fittings & connectors, they have a much larger hole which allows for more airflow so your tools will make more power than with the smaller type A or M that most people use. I recently replaced all my fittings in the shop because I had an assortment of all things air from 20-30 years of acquiring. The advantage of type V couplers is that you can use tools with type A & type M fittings along with the type V kind of a universal receiver however the reverse is not true, type V fittings WILL NOT work in type A or type M couplers. If you are using them for home shop, type M is fine the ones I have are working great form, fit, and function are great.

are they made In USA?

I looked and cannot find a marking that indicates whether or not this is the case. But, they are machined precisely and work well, which is the key thing. Given the present attitude about mining, I'd guess the copper came from Chile, the zinc may or may not be from the US, and the steel is probably a US product. If they can be made by extrusion and/or cold heading they are probably a US product.

Are they still made in the usa?

Indeed they are, which is why it's my brand of choice. Below is a link to their website for this product.http://www.miltonindustries.com/couplers-and-plugs/m-style/12-piece-m-style-coupler-kit.html

Will the quick coupler fit on a Porter Cable PCFP02003 pancake compressor with 3/8 inch hose? Thanks

They worked on all my 3/8" hose connections as well as my compressor

If you want to avoid leaking fittings, buy these

The Milton couplers work well with my rolair compressor and air hoses. I had purchased some cheaper versions at a big box tool store that didn’t work out so well (leaky). All of the Milton plugs fit well and don’t leak.
