The Ultimate Guide to Fittings and Couplers for Air Tools - Gear Up With Gregg's

While I enjoyed this refresher, mating all my plugs to various couplers did not result in them multiplying when left to their own devices. I was really hoping to leave them in the dark for a few days and come back to 4 new generations of offspring.
At least I don't have to any paperwork for the new adoptions.

Can you put a high flow coupler directly to your compressor?

When I was a young Bloke there were three styles of quick connect fittings. There were RYCO and PEM. There were different diameters for different air capacities, but none was intrinsically better than the other.

In the meanwhile every manufacturer wanted in on the action(profit) so everyone said that theirs was better. They were all basicly same but they had to be of different design so avoid patent problems.. As a result there are about 12 different styles which don’t connect with each other.

For 60 years I have standardised on RYCO because it suits me.

Are female sockets normally closed air tight and open whenever a male plug is inserted into them?

wow this is cool

Thanks! Best explanation I’ve heard!

Great video, Great pictures and GREAT clear audio.
Thanks!

Excellent info! Also shocking to see that thread size doesn't matter and actual standard plugs found are rated higher than though. Makes you wonder if the latest high flow popularity is justt a marketing trend.

I like that universal female coupler. I have an air tank with a 1/4 output with a female 1/4 coupler. Do u have a conversion coupler from 1/4 to a 3/8 female coupler ? Reason to run power tools like air wrench.

I dream of a world with only 1 standard for everything ,and that standard would never be changed untill new product is 50% better than old one. This way everyone pushes the water to its own water wheel and you end up with 50 standards that do same thing.

Guess im out of luck ,my chinese compressor came with female coupler which is god knows what and i have to go buy a hose -but ofc none of those sellers know what they are selling or which coupler it is .At this point making my own hose and ditching chinese unknown coupler seems appealing idea . But god knows what thread they used aswell,and everything is extra suprise expense.
Too bad i dont live in canada . . .

Why was I told nitto fitting has better air flow than M style fitting when it's not?

Are air tools being replaced by battery?

Nice video thanks

I've used them all and none is better than the Flexzilla brand. The 1/4 inch size flows almost as much as the 1/2 inch. While the Flexzilla will work with other brands, it is best to go all Flexzilla for the best flow and most reliable seal and function.

Can you run fluid through these?

Thanks. I'm almost 32 and bought my first compressor. I wasn't aware that there were so many options.

💥 Would LOVE to see a chart showing how much force at 120# is needed to 'couple' these different styles. 👍😎✊
The hi-flow Milton's are insanely difficult at 120#

Nothing less than a 3/8 hose and I use 1/2 hose most of the time on trucks

YOU ARE MORE BORING THAN MY GRANDMA AND SHE IS IN THE CEMETARY NOW FOR 30 YEARS....

Listen, if you are here like I am, it means you are not an expert. In other words, you are running an air compressor in your home garage and not some huge industrial application. Given that you and I are probably similar people, I will use my numbers to make this point:

My compressor puts out 5 CFM at 90 PSI. The lowest CFM number he just gave for a coupler is 34 CFM. Ig the most you can produce is 5...then couplers that handle 34 will be 29 CFM over sufficient for what you are doing, and 40CFM won't produce anything extra for you.

The connectors I found today are type M. The plugs I found are type D. I actually came here hoping to validate my purchases, by making sure those two types were compatible. I watched this video just like you did, and just learned that the difference is 34 to 40 CFM, one to the other...for my 5 CFM compressor.

I'm set.

Like the video but the background music drives me crazy. It's to distracting.

Buying a pack of f&m connectors is a sure way to make sure they always mate up.

Commenting on the video for the algorithm

Great informative video. My husband was diagnosed with Young Onset Alzheimer’s, so I am the one doing all the home repairs now. Our air compressor had the tire inflator end. Unfortunately I have no idea where he put the other accessories. We have a Rigid air compressor that came with everything including the brad & nail gun. The compressor itself uses a 1/4” quick connect coupler, that match the tools. However I want to be able to use the compressor for other things. Now I know how to determine the plug type on the tools, so I can by additional accessories “again” 🤪 Thanks again for the video.

Great Video Learned a lot.

Hello! Is there a socket designed to be “open” when disconnected?

Loving these jams, Greg

Bought a house with air compressor and lines already installed in garage. Have all female couplers. But Have no idea what I’m supposed to connect to them . He installed all copper lines so you could connect with ease wherever you’re at but once again, I have no idea what to buy to be able to connect to the female coupler. I’m assuming I have to remove all 6 that are loctite on and replace them all and start from scratch.

respect from Turkey bro , good video

This should have been standardized a long time ago.

I'm having to use my compressor for the first time and my head is spinning! hahaha Your video is incredible. I'll be watching it many times over! hahaha Thank you. You teach well.

My compressor regulator only has the gage move when air is flowing threw it ? There are regulators that allow you to to reduce the psi without any pressure moving .
Whats f to h ex difference?

And then is the BSP (British Standard) which is very close to a NPT type quick connects. The threaded tapers are a bit different so they are not met to be interchanged. Then there is the BSPP (British Standard Parallel Pipe) pipe thread standard which is basically a straight thread. I ran into this when I bought a HVLP Paint spraying gun trying to adapt to my current air tool NPT system of disconnects. I'm 66 yrs old and been in the mechanical field all my life and hadn't dealt with the British systems much. The consumer grade HVLP paint guns are made in China which mostly use the BSP and/or BSPP type standard or a slight variation of it so I had to go through a learning curve to make sense of those type connectors.

If you felt horny listening to this you need Jesus in your life!

So many of these leak air. I have using Melton coupler for years and very happy with them.

55 and in the trades. Never knew there was a universal female socket. 😮

😵‍💫 it's simple, but when you have different sizes through our a facility ordering the correct one becomes a task

Autobody shops generally use higher flow systems than A, because DA's are air hogs. The body shop I worked at had a screw compressor which delivered high flow rates of air and the larger couplers and nipples to accommodate the required high flow rate

you forgot to explain what air is

Why does my hose keep trying to knock me out? I replace the coupler and it’s fine for a few years. Then it’s looking for a fight again. It’s no fun to get hit it the face with a coupler.
Any recommendations to avoid this?

Great video. Thanks

Gear up with Greg, but with Dave??? 🤣

Excellent!

only with a lot of experience you can make such a good video, thank you

Thank you for recording and posting this valuable educational video

So ja the universal female coupling can fit 1/4 and 3/8 male coupling?
