Review: Best of both worlds. Use high flow or normal connectors. Strong spring. Overall a really nice quick disconnect. - This is a very nice quick disconnect. It shoots the tool off the end quickly without losing much air. Even if you don't use the high flow connectors this is a nice female end. The real benefit of this is that you can use the normal flow and the high flow ends and switch back and forth. Some tools such as an impact wrench benefit from the high flow connector more than others. (paint sprayers might benefit as well) Milton makes great quality products that as far as I can tell haven't changed much over time. Quality brass with strong springs. Install it with teflon tape to make sure you don't have a leak. Put the tape on in the right direction so that screwing it on won't undo the tape. Brass is really the way to go if you don't like leaks and Milton is a great brand for compressor accessories.
Review: Best coupler yet! - I have been using couplers from various suppliers, and lots of ones from the discount tool store. However, the ones on the end of my main air hoses tend to see allot of use, and end up leaking after 3 to 6 months. This one has been in service for a couple of months, and shows no sign of premature leakage or wear. It is great. I should say that this coupler works differently from many other common couplers. Simply push into it and the male end locks into place. Similarly, there is not a need to detension the couplers to release, simply pull back on the release ring. I like that, but it is different from the other couplers I have. 10 year old kids will find this coupler easier to disconnect than the others which require more strength and additional dexterity.

A: The NPT side is 3/8".  However, the coupling side fits standard V and I/M style fittings, which are considered 1/4".

**Q: Anyone know the diameter of the "coupler body" itself not the threaded side? have to fit through a 3/4" hole. and, i have the 1/4" spray tips. thanks.**
A: Max diameter is about 0.910 inches.

**Q: Are the parts that are not brass stainless? the springs and balls?**
A: All the parts I can see are brass. I don't see any steel. Then again I can't imagine the spring would probably be steel.

A: No there is no dust cover for the V-Style couplers.

### ⭐⭐⭐⭐⭐ Backwards compatible!
*by D***N on May 16, 2019*

I like how they work with the standard industrial type fittings. I noticed an immediate difference on how quickly my tires pump up. I noticed a difference at how much torque my impact gun has. I have yet to try a paint gun with it, but from what I hear, it will also make a difference. Great product, had no issues with quality whatsoever. I prefer brass to any other metal when it comes to air fittings.
