Default Best Pneumatic Quick Connects ?

Does anybody know who makes these pneumatic quick connects ?
Trying to sort the most reliable ones and these seem pretty nice.
I have had the tangs on the Robart ones fail under pressure before, so a bit hessitant on using them.

Same for me, if I'm putting any kind of quick connects in a semi-permanent location to make for easier gear or valve removal, I like Festo push connectors. At wing joints that are frequently disconnected if I can't make BVM EZ-air connectors work, I have never had a problem myself with the Robart twist lock connectors. I don't like the aggravation of the pictured style that requires multiple turns while I'm precariously balancing a wing and trying to hook things up at the same time.

I use BVM's connectors. They are kind of a pain to fasten and unfasten. But, I have had a Robart connector fail to engage properly. When I retracted the gear, all the air escaped and then the giant p-40 cart-wheeled on the resulting belly landing. Basically I hate air operated gear But I have been stuck with it on the two BVM planes.

BVM mostly uses very small air lines. The smaller the line, the less air used for an actuation = more actuations and less weight.

If you want the info, you might want to consider taking the time yourself to look them up online!

They look similar to the Airpower airline disconnects, which I really like. I have used them for years and never had a problem.

I use Luer Lock connectors, a medical air line connector which has been available for model use from various hobby suppliers over the years.

https://www.drifton.eu/shop/108-fitt...nd-connectors/

Easy to grip with fat sausage fingers, no O rings to perish, light, available in different colours, never had any problems.

Last lot I bought from KMRC Jets.

I've been using the Robart ones for decades and have use the ones shown by the OP.

Both have worked for me as they should for years, no failures.

These are what BVM included with an E-brake I got from them, I just didn’t know what they were called or who made them so I could not recommend. They work quite well also.

Until ......

Was happy with these for years until an O ring split, fortunately during a pre flight, leaving me stuck for the day.

Lesson learnt, pack a couple fresh spares if continuing to use them.

Bad experience with all the aluminum style the wi oxidase after some time and difficult to work with, only the robart quick connectors and the festo style ones
