I had to make one last post.
In this video, I asked my partner Justin Medlin to demo an air ratchet connected to a Goodyear whip hose via...
I appreciate your comments.
My law firm has been doing quite well off of us, thank you:(
When I started this thread I was just having fun teaching my apprentice about product design and manufacturing and this thread documents a fair amount of it.
Thank you very much for the support.
I showed this post to my associates to make them smile and all of them did except for Deb who predictably said "but he didn't place an order did he?":)
I just found this post so sorry for the delay.
Let me start by saying I don't answer these types of questions.
I design all my devices to operate within certain parameters.
I would be happy to supply temperature and pressure ratings.
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...
Here is a short video I shot moments ago to demonstrate that I actually use these things and have been for some time.

Shown here is one of my early generation Orbital QuietPlugs I use in my prototype shop.
I've been using it for many months and it has never leaked and the freedom of movement is as good as new, maybe even better.
The air pressure as shown in the video was 165 PSI.

This is about what you can expect for the "Orbital QuietPlug HF" and also for the "QuietHose" fitting.
The standard "QuietPlug" is less because of the smaller bore.
I don't have numbers on it but the flow rate is at least 5 percent greater then a standard plug.
The answer to your first question is "YES".
I don't have the flow/pressure data available at the moment however I can state that the flow rate of our standard "QuietPlug" is actually higher then a standard 1/4" plug.
