Ok, Documentary might be a bit fancy of a word for me, But I had to wear those earmuff hearing protector thingys so this is not your ordinary video!
Later I'm going to test this in actual real world situations with some tools, but in the meantime, here is evidence that should alter your decisions on which fittings to use!
Findings:
(purple) V style flowed 15.25 SCFM
(red) M style flowed 11 SCFM
(green) A style flowed 11 SCFM
(blue) T style flowed 11 SCFM
Bores measured:
(purple) V style 0.3"
(red) M style 0.2"
(green) A style 0.2"
(blue) T style 0.2"

Bill Nye the Science Guy! Interesting video buddy. I've struggled with a giant air compressor and never getting enough volume for years. This nails it. Too bad I'm wallet deep in Milwaukee battery tools now. I have a 8' vertical compressor that is virtually brand new sitting in the corner of the garage and hasn't been used now for a couple of years. Things have changed. But not your channel. Another great episode. Thanks!

@trythistv 4 года назад

I've noticed a distinct difference using the V-Style fittings for things like my impact or air hammer. This video seemed a little slow to me, but it also answers the question why there was such a difference with the same hose, same compressor and same tools suddenly having what felt like double the power. But cordless tools have indeed come a looooong way, I've got a bunch of older Dewalt 18v tools, I've highly debated moving to Milwaukee tools, but haven't done it yet, they seem like real quality stuff. I use my 1/4 impact driver for all kinds of stuff, rarely do I need the air tools, but especially when doing suspension work on the cars or trucks it seems like the 1/2 cordless doesn't have the oomph when the air impact rips bolts right out like they were hand tight. Just did a pile of work on my blue w123 mercedes, new ball joints, new tie rods, drag link, steering stabilizer, what a difference getting those old rubber parts replaced. I need to do the lower control arm bushings but I dread the thought of it. I'll get to it eventually.

@rightcontractingncsf4561 4 года назад

Thanks for your channel. I wonder about the flow difference between an 'H style' fitting (3/8th's Industrial) and the high-flow 1/4 'V-style' fitting.

@trythistv 4 года назад

I've just found the Milton H style ends, they do come in 3/8 and 1/4 npt, I've added a pack of the 1/4 npt to my Amazon cart. I suspect they are quite similar to the v style. Since I have "3/8" hoses they all have 1/4 npt fittings so I'd need to redo my entire air system up to "1/2" hoses to be able to use the larger npt fittings but I will certainly take a look at the H style that use 1/4 npt! Thank you for the compliment and suggestion!

@RK-kn1ud Год назад

With a quality air source, 1/2" hard line, 3/8" soft line (from the hard line to your air tool), and normal M style fittings, I find that will usually handle 99% of what comes through the door. That said, from my research (including your video), a V style fitting may make a difference between being frustrated with that 1% of jobs or finishing them with less effort. Thanks.

@trythistv Год назад

That is pretty much exactly my findings. Most tools do not benefit much from the v style fittings. Big consumers like impacts do have a marginal improvement, enough that a bolt that won't quite pop with a m fitting often will with a v fitting. That being said, I have run into plenty of miserable fasteners, pto couplings on seadoo engines can be a real pain too. Even a 3/4 gun doesn't always bust em loose. My 3/4 gun may need a rebuild though.

@jeftesantiago 3 года назад

5:26 Your caliper says 0.3 inch, that means that the bore size is 300 thou, not 3 thousands, 3 thou are 0.003.

@Titans2138 4 года назад

what about further boring out a v-style connector with a drill bit or rotary tool? I'm sure the walls are more than thick enough, they can handle being thinned a bit

@trythistv 4 года назад

Quite possibly. I'm unsure of how large of gains could be made, I suspect the coupler may be the limiting factor. It is also thoretically possible to use H style I believe they are which are stupendously enormous fittings, at some point I will retest to see if the coupler or the plug becomes the bottleneck

@jheissjr Год назад

A second way to test flow is to attach the fitting under test directly to the compressor tank output, leave the fitting unconnected (don't connect anything to the NPT threads), and time how long it takes to empty the tank from 100psi to 50psi. Double the time is half the flow. I believe flow rate is nonlinear and decreases the higher flow. Flow testing by emptying the tank removes the hose and provides a measurement at the highest flow rate where the flow is most impacted. I would be interested to see flow vs psi with your rotameters at a couple PSI values to plot the data.

@trythistv Год назад

I need to do a followup on this soon, I've got some more assorted types of fittings, and I could easily do several tests like you suggest, as well as re-doing some of the rotameter tests, perhaps even fix up some of the plumbing and make a better test rig for this.

@polocash11 3 года назад

So it looks similar to 1/4 to 3/8 comparison. My tools are based on cfsm at 90. So do I need to adjust for this? I am totally new to this, so I hope I am making sense.

@trythistv 3 года назад

Right, the v style basically have the airflow of a 3/8 style fitting but in 1/4" size. And most of the tools are adjusted for 90psi, not cfm, in which case as long as you leave your regulator at 90psi your tools will get the same pressure but more cfm through the higher flow fittings so they might make a little more power, those restrictions can actually drop the pressure so the regulator could be set to 90 but with several fittings restricting the flow your tool may only see 70psi under a load, while with the high flow v fittings it may see 80 under load. I should do this again with a gauge on both sides of the flow meter and apply restrictions and see how much pressure is lost

@polocash11 3 года назад

@@trythistv So if I switched to 3/8 fittings, would it be the same? I am thinking I would need 3/8 hose to keep the rate of air flow? But would 3/8 hose work on these?

@badmatt4227 3 года назад

Hey, Stedlin claims they get the same flow as the high flow. Can you include that brand in your next test?

@trythistv 3 года назад

I plan on testing some of their fittings soon! I suspect the price difference alone is going to deter me from rebuilding my air system, unless they are absolutely incredible, we will see!

@badmatt4227 3 года назад

Thanks, I understand that the I.D. of the plug is part the equation. The other part is the coupling, I learned some couplings restrict air more the others. But, I do not know which ones.

@randomnetwork1995 Год назад

Okay but is there a difference between 1/4 hose and 3/8 hose. And also from 25ft. Compared to 100ft.

@trythistv Год назад

Absolutely. One of these days I'll have to get this stuff back out again and do some more tests, But I can assure you, any restriction is for a certainty going to lower the potential power output of a tool. Big shops often run 1/2" hoses with giant fittings to their 1" impact guns and such, they would run off a smaller hose, but not have nearly the same torque.

@RK-kn1ud Год назад

@@trythistv I wouldn't run less than 1/2" hard line. 3/8" soft line from the air port to your impact gun is usually sufficient unless you are constantly dealing with Heavy Duty rusted trucks.

@ginfizz20 Год назад

How about drilling out all those small dia fittings?

@JCcanU 2 года назад

What Air Compressor did you use ? Home shop, most have 20 to 30 gallon tank with a 1/4 outlet The Tank has a welded in fitting can not change it out , I think its useless to go to a larger fittings unless you have a 60 plus gallon tank with 1 inch or 3/4 outlet at the tank . can you test a tank with a 1/4 inch outlet and go to 3/8 or 1/2 inch . with a small hole and going bigger your defeating everything . I worked with a lot of tanks 1 inch outlet to 3/4 to 3/8 hose 1/4 inch fittings . big to small . never backwards 1/4 to 1/2 Useless in my book .

@trythistv 2 года назад

At the time I was using a little 20 gallon Craftsman compressor, 1/4 inch fitting welded in the tank just like you said. Going to these fittings made a dramatic difference in performance of some tools. Its not a huge difference like going up to 1/2 inch hose and fittings with a bigger fitting in the tank, but maximizing the CFM makes a fairly noticeable bump in performance. I now have a 80 gallon 5HP compressor that has a 3/4" fitting in the tank. I get the same performance using these fittings (as you would expect) I am very curious how it would work going from a small fitting to a larger hose, might give more of a burst of power from the added volume in the hose. I'll have to experiment with that sometime!
