Quality no-leak air line quick connects?

[Bruce Page]

I’ve been fighting small air leaks in the quick connects for my 3 coiled air hoses. I’ve already been through the mostly junk quality that the borgs offer.

Can anybody recommend a quality quick connect?

Anyone have any experience with these?

I’m actually using the ones from Lowe’s but I had a few that had to be exchanged to get ones that didn’t leak. The ones I have are working well now though and I like the push button pressure release.

I only use Flexzilla connectors, quick connects and hoses and so far Ive not had any issue with any of it. I believe they are made by Legacy?

[Bruce Page]

Ben, have you checked them lately? I bought this set from Legacy in 2014: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
No leaks when I installed them in 2014 but today when I dunked them in a bucket of water all of them were leaking, even the one hooked up to my seldom used portable tank.

Those and the ones on flexZilla website are normal couplers, right? Based on your first link I thought you were talking about the style with the push bottom release to break pressure before releasing the plug from the coupler. I have flexZilla hose and switched from the ones you linked to the push button style and love the ease of disconnecting tools.

[Bruce Page]

Yes, they are normal quick connects. I'm looking for a higher quality connector. The push button release that I linked to would be a nice benefit but not a requirement. When I worked as a machinist years ago the shop used Schrader quick connects. They were high quality industrial but a PITB to use. McMaster Carr sells them for $42 each. I would like to find the same quality level but more user friendly.

I switched over to the Prevost high flow fittings a few years ago. Only downside is they are not compatible with the normal generic fittings. Besides that they rock, no leaks, easy to connect and great flow.

Atlas Copco profile type 33 quick connect. They are robust and leak free for many years. Single push button types are not the best. The AC ones are rated for breathing air so if you can't find them, look for ones that are built to BA standards. They will do what you want. Cheers

I think that part of the issue with these kind of components is that despite "standards", there are enough minor variances between brands, etc., that small leaks are almost to be expected when mixing things up. I will hazard a guess that sticking with one specific brand across the board will help with this, such as those that Chris and Wayne mention by example. (I'm sure there are others, too)

I currently have a mixture and am sure I lose some air as a result.

I had switched to this new style where you don't have to pull the outer sleeve back when inserting the male end (you just push it in). They started leaking after a few years.

I think based on other threads on SMC, I ended up switching to Milton-brand "regular" QDs, and they have been leak-free. As Jim said, I suspect brand standardization is important - in my case, I went through and replaced every M and F end all at once with Milton fittings.

[Roy Petersen]

I just use the ones from a local auto parts store. Under $10 per female and $6 for male ends. They don't leak, and as long as you don't mind the slide collars, easy to find. Amazon has something like it:

Thanks for the info, there's a lot to sift through.

Jim, that was exactly my reasoning when I installed the Legacy set in 2014.

The Tru-Flate ones are as good as Milton.

I think a cheap fix is to upgrade the o-ring to a quality one. I wonder if silicone ring would last longer. They are fairly easy to rebuild.
