## Questions & Answers

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

**Q: are they made In USA?**
A: 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.

**Q: Are they still made in the usa?**
A: 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

**Q: Will the quick coupler fit on a Porter Cable PCFP02003 pancake compressor with 3/8 inch hose? Thanks**
A: They worked on all my 3/8" hose connections as well as my compressor

## Customer Reviews

### ⭐⭐⭐⭐⭐ Milton quality!
*by L***D on April 17, 2025*

My shop has many air tools, and swapping out tools happens frequently. I've tried cheap connections before and they will leak, jam and fail too much. Milton parts don't cost much more, and they function much more reliably.

### ⭐⭐⭐⭐⭐ Milton air hose products have never failed me in over 55 years
*by T***D on July 27, 2025*

Very well made product, easy to connect to my air hoses and all my air tools. Better made, in my opinion than any other air hose connection products on the market.

### ⭐⭐⭐⭐⭐ Excellent!
*by M***Z on September 11, 2024*

Bought some "top quality" ones at Walmart, nothing but junk and leaked air like crazy no matter how much Teflon tape you used! Bought these here to replace them and they work perfect and no leaks at all, excellent quality!
