Air flow quick connects

[R6 Racer]

Im trying to find a thread i read a long time ago.
Someone had done some testing on air line quick connects for actual volume.
What I am trying to do is make a decision on which QC I should use to maximize air flow & I also like to get an idea for what brand or type is easier to use.
Any help finding that thread or any thoughts on either flow or ease of use would help

Thanks
Steve

And then buy from Stedlin. His quick connects are fantastic.

no tangible evidence but i just recently switch from L type connectors to V type and there was a noticble improvement in power and speed in all my air tools.

I recently bought a Stedlin kit, they worked as advertised with a noticeable significant reduction in force needed to connect and disconnect. My only concern is price and I have to buy another couple of kits to change over all of my devices, but this is the case for all upgrades

STEDLIN! Buy once, cry once.

FWIW I have two tools that genuinely need high flow. Mostly high flow is not an issue. So know that about yourself.
Here's the recent thread:

Easy to use push to connect air hose fittings?

I'm doing some improvements to the garage and need some advice or direction on some easy to use push to connect air hose fittings? My grandfather has some mobility issues (neuropathy, arthritis) in his hands but i want pneumatic tools to still be accessible for him, if possible. I purchased some...

Recent thread was focused on "easy to connect/release" as our hands get older. There are some fabulous products linked in this thread and Stedlin posted a lot of info about his products in there.

I switched over to all Milton V connectors now, noticeable difference.
I wish the stedlin offered the v flow, then it would be a no brainer.

Switch to Milwaukee, problem solved.

I designed a coupler that is compatible with the CJEN-320 (V style) plugs and decided to not sell it as it makes no sense when used with 1/4"NPT air tools.
For example:
A 1/4" NPT HiFlo coupler design such as the one Milton markets as the "V style" will flow up to 45 CFM with only a 5 PSI pressure drop using a common industrial plug (M syle). Switching to a large bore (V style) plug will yield even a higher flow but that's irrelevant since no tool with a 1/4" NPT connection will consume that much air.

Who is making that claim about no 1/4 tool will consume that much air? I use the V for air blowing, tire filling, sandblasting, and for sure the volume makes a noticeable difference. So maybe not for some tools, but there are times its nice, so why not make them? Im sure if you had ones with a easy disconnect and the best flow, hands down you got the market.

I am.
When you state it makes a difference what are you comparing it to?

personal experience when i switched from M to V, made a big difference in flow. I use to blow out my shop with the M and when i switched it was night and day how much volume it was restricting. My air grinders also use to fall flat, now they seem to have no end.

An M style coupler with an m style plug is very restrictive but the vast majority of the restriction is in the coupler not the plug. That’s the point.

sorry you have me confused now.
you started off saying that a V coupler is not needed as it doesnt flow to a point where tools can benefit it when using a M plug. But you are now saying that a M coupler is what is restrictive.

I guess how does a Stedlin coupler + Stedlin plug flow compared to a Mc+Mp and compared to a Vc+Vp.

Not trying to derail the OPs post, but he is looking for a good flowing connect .

Flow is dependent on input pressure and pressure drop.
The higher the input pressure the lower the pressure drop will be.
At 100 PSI input and a 5 PSI pressure drop a Milton m style coupler and plug will flow 15 CFM.
The same plug in a Stedlin coupler will flow 26 CFM. The Stedlin coupler and full flow plug will flow 32 CFM. This is all at a 5 PSI pressure drop.

Thanks for the info, wish i knew about what your company had to offer when i switched to V. If you ever decide to make the V compatible coupler, i would change all mine out in a heartbeat. Just doesn't make sense to change all my plugs out now.

 

[Stedlin]

The CEJN 320 (V style) standard was originally engineered as a safety coupler.

The plug was not intended to be used unsafely as it commonly is today.

The large bore makes it extremely unsafe to disconnect under pressure and I will never support that.

As a matter of fact I have permanent hearing damage in my left ear because an associate disconnected a high flow coupler at 150 psi as I was walking by.

Thank you guys. much appreciated!
