Review: Missing parts. Part found - This product arrived on time (actually early) and is of excellent quality and fit and function is perfect. However, the package I ordered is described as having two 715 couplers, 8 727 male plugs and 2 728 female plugs. It was missing one of the 728 female plugs. The package was not opened and arrived in tact just missing the one 728 female plug. It seems to be a quality control issue with the package. It would be nice if it were easier to solve this issue without having to jump websites to address it. Part found. I would like to apologize to Milton for my first review. I actually found the fitting that I had originally said was missing. Apparently it had rolled off of my workbench without me noticing and I found it today while I was cleaning up. I have no problem admitting that I was wrong and I should have done a better job of looking for a missing fitting that was more or less directly in front of me. I am changing my rating to five stars because as I said in my first review the product is excellent in quality and performs perfectly. Again I appreciate Milton’s understanding my human nature and acceptance of my humble apology.
Review: Quality USA made air tool and air line connection from Milton! - Milton “M” style air tool and air hose couplers. These have been around for decades and are still a standard in most garages. Good standard airflow for most uses in automotive applications. Smaller size than bigger super high flow types or universal connectors. Rust proof brass connectors that are not affected by a little water. This is a great starter kit if you just bought an air compressor for home. Positive seal prevents air leaks and hissing hoses. Overall a great design. These tool fittings are steel and a few grams heavier than aluminum fittings… but I have dropped an air tool with aluminum fittings and they snap off when they hit the ground.

## 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

Very good quality! We tried cheaper brands, but they start leaking after only a few months of use.
