I am extremely impressed with the way the female coupler release sleeve stays pulled back, till you insert the male coupler it snaps closed so slick. Literally you can snap them together with thumb and forfinger of the same hand you are holding the hose and air nozzle in!

Love the push to connect feature. The increase in airflow makes impact guns work much better. I didn't know what I was missing out on with 3/8 hose size until I got these!

These worked great. Increased my working pressure by about 5-8lb on my spray gun

These fittings are well made lock together very smoothly with no leaks. Threads are cut well gave no trouble when tightening. Vastly better quality than the cheaper brands I've tried.That being said, the packaging is terrible. The fittings come sealed between a cardback plastic cover. The problem is, these fittings are heavy the adhesive holding the packaging together is weak. The first package I received was busted open missing 3 fittings. The replacement item was open as well, but fortunately all the parts were in the envelop. The parts got scuffed up rattling around but I count it as a win that I didn't have to reorder a 3rd time. For the price you pay, it'd be nice if Flexilla would give you a plastic case to store them in. Or at least fix the packaging, then they'd be worth 5 stars.

I love everything flexzilla. When I found out about high flow couplers i immediately searched for Flexzilla and saw they had their own. They installed smoothly into my flexzilla hoses and they work great.Pros: Great qualityCons: You're still reading this and you haven't purchased it yet!

I like the connectors. they have a pop on connection. you open them . then when you put in the plug it closes easy.

Best for your money!

Purchased a few more over the years. Great addition to any air tool. Not sure if its ACTUALLY a high flow or not, but they work great.

Great quality and easy to use. Also, no air leaks

Very nice fittings. High flow. Just push to connect quick connects.

These are very well made. As I have come to expect from the FlexZilla line. The only thing I didn't catch and it was my fault, is that these fittings are slightly different in there design from my previous typ of air fitting. The type I have now is the (Industrial) class connector. The FlexZilla is a cross between the Industrial and something else. It may be there spin on the design, I am unsure. I am not an expert when it come to all the typs. Here is what I found.My old (industrial) male connector end will contact to the new FlexZilla female quick coupler just fine,no leaks or issues. But my (industrial) female coupling will not except the FlexZilla male fitting. It will not go in and lock in, it is to big. Over all I would say that I like the fittings and would buy them again. When needed I will replacement the old ones if and when they start to leak. The issue with the fittings being partly compatible isn't to big of deal I will eventually have to replace them all so I will just chang over to FlexZella fittings. As they clame they do have better air flow through the fittings. That's why the fitting is bigger.If you are looking for a good fitting set I wouldn't hesitate to buy this set they are good and well made.

Good value

This my second Flexzilla swivel and really enjoy using it my automotive maintenance services. We'll buy again.

Finally, decent air couplers! Took me a bit to realize these are a push connect set and not the traditional type. They lock up GREAT! These are the larger male fittings, so the female couplers are meant to take them. Bonus point is, even the smaller fittings will lock up in these couplers, they don't even leak. These larger fittings will NOT fit my older couplers however (no surprise there).Leaky air lines are like nails on a chalkboard to me, I can't STAND it. I'll be abusing the hell out of these, if they survive the summer, I'll replace every tool, every hose and all wall ports. Mine are getting pretty worn out.If you haven't yet, check out their hoses. Takes 2 minutes to cut a hose down and put a new end on it. I picked up, I believe, a 50' hose and have been trimming pieces off it for shorter lines for my paint guns. High visability, easy to see, super light, doesn't kink.... We'll see after a few months use.

The quick connects are great the fact they are slightly bigger it doesn't restrict the airflow!

As with all the Flexilla stuff I've tried, it's nice and works well now, but seems lightweight and not heavy-duty. More a home shop/garage part, probably great with light/occasional use. Swivels well, fittings machined properly; will keep and use but will go back to Milton's and Speedaire's domestic parts.

I bought these to put on a Flexzilla hose to use with a 26 gallon Kobalt compressor. The quick connects don't seem to fit any of my tools or connectors. This is some weird proprietary size maybe?

Great Quality Construction and anodized finish, High Flow and accommodates most types of quick connects. Passes my 45cfm at 400 psi with no effort. Easy push in self retracting collar.

Works but will break easy

Works with old and new adapters. Wall thickness is less to increase air flow, so not sure if they are as durable as other adapters, should be fine for garage use.
