Brass 1/4 Inch NPT High Flow Air Coupler and Plug Kit, Air Hose Quick Connect Adapter, V Style, Air Compressor Fittings, (28 Piece)

These are very well made high flow air fittings. I love the easy connection to the coupler without having to pull back on the coupler itself to attach a hose or pneumatic tool. Fit is tight and leak free. Definitely better than the the aluminum ones I have used in the past. Lets be honest. If you are buying aluminum air fittings for weight savings, then you are kidding yourselves. These are air tools, not screwdrivers. They are meant to be sturdy and well built. Great product.

Seem to be excellent quality no leaks so far time will be the test

Being at the third round of changing all air quick couplers in the workshop, these seem REALLY promising.They got everything right which has been an issue with the previous iterations of couplers here:> Brass bodyThe previous I had were a steel-aluminum mixture that would corrode internally.> 6 Retention ballsI had issues with other manufacturers that would leak when the coupler is pulled sideways. These hold tight.> High Air flow - larger internal diameter compared to other styles.That can have an impact on air chisels and other high flow tools.> Compatibility with other MFG.The type B plugs I have around do work with these V-style standard couplers.> One hand insertionNo need to pull the sleeve back for connecting.And then a fabulous price for 28 pieces of turned and knurled brass hardware.

These are great and I've installed them on all of my non-rotational, non-impact tools, including tire inflation chucks, paint guns, and air blower guns. They work great in those and, when used with a Milton V-style female connector, are leak-free.Milton, an industry leader for air connectors, recommends against the use of brass V-style plugs on air tools, writing "NOTE: The use of brass plugs with air tools will cause premature wear on the couplers and plugs." They also have this note next to the steel V-style plugs: "NOTE: Steel plugs are highly recommended for use with any kind of percussion tool such as impact tools, grinders, polishers, drills, etc."There are photos on the web documenting such wear both for brass plugs as well as for aluminum ones. So I have some steel plugs for use where brass is not recommended.

used these for my supplied breathing air hose in our spray foam trailer. The original connectors restricted the air flow greatly and caused the air pump to run higher amps and run hotter. The flow rate increase is very noticeable for this use, so I'm sure if your looking to increase the flow rate for tools or painting these will do the job.

The media could not be loaded.  Because of the price I thought this was a super deal but when I went to use it, I noticed I had an early show in the picture I have the black one is a husky and where I have it circled, you can see the ring on the husky is a lot thicker which means the husky would clamp in a lot tighter and not leak

I tried these on my new air chisel and impact gun. The air chisel I used for about 30 minutes and could no longer separate the two pieces. Then I looked at the fitting I had on the impact and it was already being mangled. These will be fine for any air equipment that doesn't subject them to vibrations. I had to return them as I have many air tools that vibrate. I bought steel couplers for my tools. To be fair I have read that brass plugs are not recommended for vibrating tools. They did have good airflow while they lasted.

I always bought the quick connectors from any of those big box stores and they always started to leak after awhile, you also needed a second hand to make or separate the connection from a wall unit. Than I found those, just push the male part into the coupler (no sleeve/ring to pull back). I disconnect push the ring/sleeve back and the male part pops out, both ways with on hand (wall mounted coupling). You can even fix them if they start leaking..... if. Before those I couldn't let my hose connected, the coupler started to leak after a few month from the weight of the hose. My hard piped system in my garage is absolutely airtight and now with the air hoses still connected no loss either. The longest time between using the air system was 3 weeks with an air pressure of 80psi all the time. With the old fittings my compressor started every 24 hrs.Best of all is the price, same price like the parts from the big box stores.

V-Style connectors, compatible with Milton, and Topring/Prevo S1 Ultraflo. 1/4’’ NPT threading, solid construction, corrosion resistant brass, high flow, perfect kit with plenty of connectors to convert tools, hoses and compressor connections. Good value at 50$. Update: they seem to be leaking a small amount of air, system used to be sealed, tightened all new fittings, using teflon, still leaking… will investigate further and update.

I was really inpressed with the quality.Great price ...Thanks again.

Used them for about 3 days in a farm shop. In that time 3 male connectors snapped off when used on an air impact, and one female connector bent to the point of being unusable when dropped lightly. Im sure they would be fine for a light duty home garage setting but they do not last at all for what i need them for.

Within a couple days the orings start blowing out of the female connectors.
