Great Couplers that Don’t leak
I needed two new couplers to replace some I had that were over 30 years old and they were leaking air so my compressor was constantly cycling on and off to keep the pressure in the tank up. I was replacing the air hose and got the new couplers so I could replace both at the same time and everything worked great together and now my compressor holds air pressure with no leaks, so it runs a lot less. The Milton couplers came in a set of four which cost less than buying them separately and since I didn’t need four I have spare couplers available if I need one in the future. I highly recommend this Milton Brand Coupler because they are made of heavy duty quality components and will last many years.

Easy to apply and remove
Works great for an air supply quick connect. The brass color looks great and the quality seems to be excellent after a few uses. Perfect fit with my supply line and was a low cost replacement.

Good quality. Heavy-duty.
Good quality. Heavy. Does what it is supposed to do. Did not leak. This product is exactly as pictured and described. Works flawlessly, no problems.

Usually the best brand I will give these a B plus they do wear out I feel prematurely
Milton is usually the brand with the best quality. However, these only have three balls inside of them instead of four like some competitors they do seem to wear out and leak prematurely.

Quality Machining Means Easy Fit and No Hissing
Milton is the "gold standard" of air fittings in my 60+ years of using air for so many tools. It connects and disconnects without hissing all the time, like the leaky cheapies do. Very good quality and tolerances, make it easy to use, so I put male ends on the tools and female end on the hose and go to work.

USA all the way!
I only buy Milton compressed air hardware. It's all still made in USA, and the quality is much better than Chinese, without costing much, if any, more.

FINALLY a OEM product
Finally I received what was described. It came in a retail packaging and ACTUALLY was a Milton product. I didn't use them yet but I've been using Milton brand for many years and never had any problems. I done expect any problems with this order. They do cost more then the off brand but you do get great quality and long lasting product that you don't have to replace every couple of months

Made in the USA quality
I am buying more Milton made in the USA products, all the fittings at Home Depot are cheap Chinese junk.

Great Quality for the Price
Very well made fittings. No leaks as of yet. The best part is that it is now easier to connect and disconnect when the line pressure is as high as140 PSI. On the cheaper disconnects it was very hard to attach and detach tools.
