Been following your progress. Saved the Stedlin site to place an order asap. You should add some reasonably priced (or even early giveaways) shirts and hats to your site to help spread the name. I like to promote a quality product.
One of our carpenter contractors who is also a beta tester was working around the shop and volunteered to do a short demo.
are they made from brass or aluminum?
hope this wasn't already answered

I'll ask again, how cold & hot did you test them to? Garages/barns/shops in the northern states can get below zero inside during the winter......which will cause many things to fail.
Pretty good demo. They look like they have a good swivel range. The noise part is of no real concern to me, but that swivel is nice. I have a couple impacts plus a straight and 90° die grinder just begging for these.

30 below inside the building where they would be kept? I've seen the inside of my barn hit 0°F (this past winter for instance).....which is why I'm asking. Leaks occur in greater numbers at cold temps, a reason we test our products to -40 all the time.
And sorry, I'm not going buy them to test them. I'll test them in a real world setting if you want to give me one to try, but when I buy a $ 40.00 product to use, I do it with the expectation that it has been tested to extremes...including pressure & temps.

That would where I would use it.
First off, I have no connection with the fine fellow that's making these fittings.
I'm from Fargo, North Dakota, and live in Minnesota now. Looks like Leveleer, the inventor of these devices, also lives MN. Duluth, to be exact, or perhaps in Superior, Wisconsin.
Now, it gets COLD in Fargo. In the eighties, I remember -94F below with wind chill (-40F below air temp). There are colder places, sure…Tower, Minnesota has the state record of -60F air temp in 1996 (I remember videos of boiling water thrown up in the air and instantly turning to icy snow, and another vid of a fellow, outside, hammering in a nail with a BANANA.) But there is something especially awful about Fargo…there are few trees and it's on the bottom of a huge ancient lakebed, table-flat, flat flat flat all the way up to the arctic circle. The wind roars down from there without mercy. It's so cold you can almost smell the polar bears while your eyes freeze shut.
But I digress.
Duluth isn't as outright miserable as Fargo…it has the nickname of "the San Francisco of the Midwest." It's beautiful, it has hills, it has beaches, it has pine trees, it has Lake Superior.
It's also darn cold, and a fair bit windy, and it has an ocean-like humidity to it that, in the winter, can somehow penetrate parkas.
So, Mr. Leveleer has access to plenty of cold. I also gather he has carpenters testing his fittings in the Duluth area (I think I read it on his website). I'd have to also guess the testing is done in the winter as well as in the summer. Mr. Leveleer might even chime in here to let us know.
Maybe I'm wrong. But I'm going out on a limb here; he strikes me as a rather thorough individual, someone who would indeed factor in the temperature when designing things.
So, with regard to the fittings working in winter, since NE Connecticut is rather less cold than the climes I mention above, I'm taking an educated guess here to say that I reckon you'll be fine.

Some interesting tidbits here, including the fact that in 2001 the US gov changed how it calculates wind chill: https://www.dnr.state.mn.us/climate/journal/historic_windchills.html

The "Orbital" fitting is rated to 300 PSI and the maximum recommended working pressure is 200 PSI.
The joint is non lubricated and the joint friction is very low at all pressures.
The effect of temperature on joint friction has not been charted as yet,
however feedback from beta testers has been positive in this regard.

I'm from Minnesota also. Been here 45 years.... and I can tell you that MOST guys who do outdoor jobs that require air hoses don't work outside when it gets THAT cold. On the few handful of days where it gets -25F and below (for example) those guys usually just take the day off. lol.

I hear ya. And I would think any trace of water in the the line would freeze solid and I sure hell wouldn't want to accidentally touch anything metal at 10F above, let alone at -40F (which also equals -40C). Ouch!
Outside of Oymyakon or Verkhoyansk in Russia, which are the record holders of the coldest inhabited place on earth (-89F, I believe), the Fargo/Grand Forks area has got to have the most people (~200,000) living in the crappiest weather conditions, summer included. I lived through actual 1930's dust storms in Fargo in the 1980's, in which towering swirling clouds of dust deposited four inches of, well, dust on the lawn. I went out with ski googles and a mask, and thought to myself, "Why did my relatives stop in this place???" as I sweated in 105F degree heat while being pelted by tiny clods of dirt.
I think Oymyakon has around 800 people surviving there…and to answer a question rattling around in the reader's head, Antarctica doesn't count as "inhabited" (not my rules!).

Placed an order, looking forward to checking out your product.
Great website( https://stedlin.com/shop/) , good info, nice looking product. Definitely got me more excited about your products then your R&D videos, ha.
Might be ordering something here soon.

Just placed a phone order with a very nice lady, looking forward to trying the orbital high flow. I did mention to her I saw this on GJ.

I'm XL. Thanks.
I understand your XL shirt shipped already but you're hat will be shipped later.
For those who watched the video from Jesse, this is the arrangement he was demonstrating.
It's extremely light except for the brass coupler.
Alas, my new super lightweight compact safety couplers are not ready for production as yet as I am still working on materials.
The production machines I have purchased I bought with the couplers in mind.

What makes your system better than a Prevost swivel coupler?
I looked at their products and as far as I can tell, they don't make any products like ours.
The upper one in the picture is a flexible (pun intended) joint that can be used in many different ways.
The lower two are intended to connect between an air tool and a coupler of the conventional variety and restrict the exhaust flow.
Here is a short video I shot moments ago to demonstrate that I actually use these things and have been for some time.

To go further with cashishift's question, your product is similar to these items:

Now as the salesman in you, beside being made in the USA, what will your sales pitch be? Not trying to be a PIA, but as I pointed out, there are many other options out there; what would make me or Joe Blow want to buy your swivel connector? To sell your item, you are going against a lot of less expensive swivels, what is your angle for making the sale?

I feel insulted to have my orbitals compared to those you listed.
There is no comparison really other then spherical surfaces and pipe threads.
I am familiar with most of the ones you listed and have tested them.
I have yet to find one that swivels freely at pressures that people actually use in the real world such as 170 PSI. Most of them lock up completely at these pressures. Of course there's the fact that mine swivels 160 degrees vs 45 or 50 degrees or so for the others mentioned.
I could go on but time flies.
this looks like a great product, very well thought out, and extensively tested in the field
we buy $10 items made in China all day long & don't question the integrity, when it fails, it's " Well, it was made in china , what do we expect?"
I'm sure the Chinese stuff has not been field tested to the same extent as these couplers have , it has merely been reverse engineered to probably lesser standards that the one they copied. \
While I can see this being more expensive than other swivels, It is lower volume sales, more than just a old swivel, and so on.
I for one think this product is well thought out, well planned and well designed.
Everyone can critisize or question as they wish, I thin it's a superb product and will be ordering a few in the next while.
I will make a gentleman's bet that in 5 years , everyone says. Wow, what a great product!
cheers , and keep up the good work, Stedlin!

Keep on keeping on! Don't listen to the negative nay-sayers, this world needs more people doing innovative stuff like this, not less! I hope a big tool company takes on your products putting them in hardware store across the globe. I hope you have your intellectual property protected, patents etc.
