[@cliffclark6441]

After 50 years using impacts some thing i might add, Any flexibility in air supply will interfere with impact performance. Use short hose as possible, And use iron or copper pipe to hose. Each time gun impacts it cause a pressure surge which is absorbed by hose. 1/2 gun needs 3/8 hose with 3/8 fittings. 3/4 gun needs 1/2 hose with 1/2 fittings. And try to never exceed 50 ft of hose. Gun will have lot more power on 25ft hose. At wall use no fittings . Do not worry about thread size going into gun. It is rated as a air orifice and even 1/4 will flow over 80 cfm which is more than any gun can use. My old CP 3/4 gun 1/4 inch thread My newer IR gun has 3/8 threads. And they both use same amount of air. The larger threads on newer guns are just a sales gimmick. I got three compressors one is 60 gallon single stage this does 90 per cent of my work. With 1/2 impact. I got 5hp two stage 60 gallon at 175 psi. Seldom ever used. With the 3/4 or 1 inch impact or sand blaster i got a 160cfm diesel compressor which is tied into the shop air lines.

If you really want to wake one up you run a half inch line from a dedicated port on the tank straight to the gun and make every fitting as big as you can. If you work in an engine shop that ports heads you tend to port everything when it's slow. It will make that grandpa gun run like the matco if you port the ex side of the old one. It will be stupid loud and still just as heavy but powerful enough to break sockets every week,

[@TotoGuy-Original]

its one thing testing for how much power you use/lose but not everyone has a massive air compressor. how about doing a test on how much air gets used between the hose sizes ?

[@tiredoldmechanic1791]

A way to assist the gun without replacing all of the air lines in the shop is to connect a tank close to the point of use and use a larger hose from the tank to the gun. A few seconds pause allows the tank to refill. Even a tank as small as one gallon makes a big difference.

[@alejandrozuniga4426]

We do that for framing houses wt a 25 gal tank from an air compressor

[@NZ_Lexus_IS-F]

I sell and service pneumatic tools at my work. We find if people are losing power at the tool, it quite often stems from what the inner diameter of their air hose is and how much it's restricting volume, lots of people forget about volume and just focus on pressure, easiest way we've found to see the reality of this is to have an in line gauge plugged in right before the tool that'll show you. You may have 110psi when not using the tool (as recommended) but then drop to 55-65psi when actually in use. Just my 2 cents.

[@darrelfuhrman8217]

Another pressure drop is the coiled hoses! On airseeders, all of the main runs have to be about the same length. Every time you loop a hose around the tower you ADD 6’ to 8’ to the hose length to get the effective length. Pull a pressure drop test on a 3/8” rubber/plastic hose vs 3/8” I nylon spiral hose. Use no air couplers, just a 3/8” ball valve, test hose, tee to restriction gauge, air wrench! A lot of people are going to only use 1/4” or 3/8” nylon spiral hoses for their blow nozzles. Another huge restriction is the hose reel!!! Hello from north east Montana. 10 miles from the Canadian border.

[@MrHeHim]

I have a old (from the 80's) 30 gallon Compressor on 220v and run it at 90psi with a 50ft 3/8" hose, it never really feels starved but i do get a small kick when the compressor comes on after a few seconds. I've used my impact gun on small tanks at a friends house, seem to struggle for air after the first 2 seconds of use. At that point i start to use it in 2 second bursts to let the compressor keep up.

[@heavyduty6697]

I’ve been a Matco guy for years. Always keep my 1/2” impact in the best condition possible. At our plant, safety keeps the air throttled down to 60 psi and we use 3/8” air hoses with the smallest possible quick connects. Makes my 1/2” impact about the power of my 3/8” stubby Mac air impact.

[@xenonram]

60 psi LOL

[@byronhaley1566]

From a mechanical engineer who designs, builds, and maintains large industrial compressed air systems; you guys a doing a good job. Without going into the detail, friction or line losses from diameter, length, and incorrect component sizing it the #1 cause of poor system and tool performance. This is also the most overlooked cause of compressed air problems, too. So if you used 5ft test hoses, you probably can't see enough difference in your test to matter; but at 100ft, the performance gaps will be huge. An easy way to tell if you have too much line losses is comparing static pressure to dynamic or running pressure. My design thumb rule is a max 5psi difference from the compressor to the tool. What that generally means to a home shop setup is that 1/4" is good for blowing dust off and inflating bicycle tires, and not much else. 3/8" at less than 50ft will work Ok for most things, and 1/2" is best and necessary if you want the best performance out of 1/2" or larger impact drivers. Again, the length of the hose (and hard pipe) matter. Higher flow and pressure compressors can't improve system performance if the pipe size is too small start with.

[@tslater1989]

I run 3/8's, used 1/2" before. It is noticable, that being said. The bulky 1/2" in a factory where you have 20-30' and you are 15 ft up, that extra weight does cause some issues. The 3/8" rubber hose is really a good compromise.

See the results of the 3/8 hose. Its a "weakest link" equation. The difference would be in the de-expansion of fully swollen hose, probably a bit longer high slope before leveling off to pure air flow, were it would join to identical to the 3/8 line.

[@joshuacoomes6388]

@@snap-off5383 I thought the same way until I had some physics training. The diameter of the hose has a different effect if smaller/larger when things are moving. Yes the pressures will be the same, but when air is moving through the hose there is a pressure drop. I think its Bernulli's equation that explains it. Yes, the small whip will cause a huge restriction, and my point may be so minimal that it can't be noticed. I dont know either, but I do believe that the 1/2 hose with a whip, or 3/8 nipple will still outperform the 3/8 hose of same length. It may be easier to see if you compare a 90 degree street elbow versus a 90 degree with a 6 inch centerline radius. The gradual bend will obviously flow more and have less of a pressure drop. The restriction the bend creates to flow can be compared the restriction and the end of a hose.

The smallest port ID will be the greatest restriction and that is usually the coupler. The ID of the hose & coupler should be the same to get the most from any one combination.

[@sumduma55]

It wouldn't matter in this setup. The air source is limited by the filter and regulator they are initially connected to. Anything after that is just minor restrictions from resistance in line size but the volume of flow is already a fixed value before the line sized come into play. This is why the 3/8 line and the 1/2 inch lines peak similarly but follow a very similar power curve. The initial burst on the 1/2 inch line is from the extra volume of the line storing compressed air volume. Once that reserve is depleted and replenished from the source (regulator), the air flow is restricted by the source more than anything. In contrast, the 1/4 inch line is actually smaller than any upstream restrictions so it has a dramatic affect on the flow rate. If they had a 1 inch setup from the air tank (supply) out to the difference in line size, your fitting argument would have a much more noticeable impact on the results. That is unless I misunderstood your statement and used 5 times the words to say the same thing.

Let’s see it again on 50’ hoses. Also let’s see the connector comparison!

[@evropej]

A suggestion to improve your source impedance or performance for the air supply: you can improve the performance of the pressure delivered to the tool by placing a small tank and the connection of the hose ( this would act as a capacitor if that makes sense to keep a constant pressure at the supply connection ). So at the end of the pipe where you connect your hose, place a small tank ( the size of a 1 pound propane tank ) to act as a transient supply ( capacitor ) for the pulsing guns. If you need better description please let me know. This would in essence give you better tool performance and data removing the air supply as a parameter. In electronics, this is called source impedance. The lower the source impedance, the less voltage droop. Power supplies compensate with a capacitor ( local storage for charge close to the load ). FYI, this is getting picky but just in case you were looking for content ideas! Also, tool designers should entertain this idea as well! Love the channel! Keep up the good work!

[@danielmonsanto8286]

This makes me wonder manufacturers do their testing with a 1inch or maybe 2 inch air line🤣 and the smallest socket possible to get the torque numbers they advertise on the box

I use the the hinge type from HF on some tools and the Flexzilla ball swivels on other tools. Also, I once saw something about how to hold an impact for maximum performance. They were saying that if you just hold it loosely on the fastener that it would perform better than pushing up against the impact like you might a drill. Makes sense to me, but how much difference, if any, would there be?

[@rednekswede1066]

Well done video, all true what you say, As been working with standard air tools and air torque tools, i can tell that the minimal difference between 3/8" and 1/2" hoses is that your tool does not consume more flow than can be provided by the 3/8" hose at that length. It will be a major difference if you tested for example an Atlas LMP 51 or similar. The difference would be in shorter time to reach desired torque.

[@mrb1864]

Good test. I use 3/8 lines at my bays as due to good air supply routing I only need 15ft hose and the short length mixed with quality 3/8 hose makes it a treat work with all day long , 1/2 reserved for longer hose and more air hungry tools .

With an HF compact impact (AKA Capri), I'm seeing over 25psi of drop at the gun from the buffer tank. Yet if I run the gun into the buffer tank output, I'm seeing only 10psi drop. So the 25ft of Flexzilla has significantly worse pressure drop than 50ft of 1/2" hose PLUS a buffer tank all upstream of it. That's a lot of fittings and such and it's STILL much better than that stupid 25flexzilla hose. It's rather baffling.

Amazon reviews: 1/2" air: DAMN! this thing is a BEAST! Its a GEM! A Unicorn! MUST BUY! 3/8" air: This does everything I ask of it and more, very nice gun! 1/4" air: The foot-lbs rating on this piece of junk is WAY OFF! I couldn't even take of my lug nuts!

[@jasonmeister1747]

I myself would love to see the effect of the several style fittings

[@mccarterjg]

Well I'll be in getting 1/2 air lines set up when I finish my garage

[@ourkid2000]

Great video! Would love to see the video on the testing of the fittings. I must say, I'm very confused by the selection and sizes of all the different fittings. A recommended basic setup (lines and fittings) that would work well for the average user would be very helpful.

[@G5Hohn]

I’ve watched this video dozens of times since uploaded. I am still digesting that even at the same dynamic pressure- measured at the tool inlet no less- such a startling difference in power can exist. It strongly suggests that we aren’t getting the same air delivery just because the gauge shows the same pressure. And what’s really striking is that the bigger hoses are making more power in the 90psi dynamic run after 5 seconds than the 1/4” hose makes at 5 seconds into the BCS run. This further shows there’s more to the larger hoses than just less pressure drop, because even at higher dynamic pressure at the gun, the 1/4 hose still makes less power. Perhaps it comes down to the pressure drop after the gauge? Hmm.

[@jameswieler3295]

can anyone recommend a filter/lubricator/regulator that uses 1/2" NPT fittings? What about a dryer? Anybody use one for air tools? I don't do any painting. Thanks

[@saltysteel3996]

All my hoses are 3/8ths, so good enough for me.

[@Kfcfranchises]

Can you do a test on some Craftsman impacts? They're at a great price point for DIY'ers and I'd like to see how they stack up

[@CodyP2000]

You could review the IR 2235TiMAX and stack it against the impact wrenches you’ve tested already :)

[@TorqueTestChannel]

We'll do just that!

[@KenyonPayne]

I'd actually like to see a comparison of fittings, we use L style at my work, curious if the hi flos are an improvement, I have an 1894

[@espeterson522]

This is an absolutely amazing video. Great job, subscribed.

[@NDC1115]

1/4" orifice at 90psi will flow 81.6cfm 3/8" orifice at 90psi will flow 184cfm 1/2" orifice at 90psi will flow 326cfm 1" at 90psi will flow 1305cfm. Hose size matters!

[@davidmattice2613]

I still believe if you look at your couplers it always knock down your size of line

[@freespirit1975]

My 1/2" Harbor Freight Earthquake on 3/8" hose to a 30 gal Craftsman compressor would not break loose a Honda crankshaft damper bolt. I switched to 1/2" hose (Milton Type M connections) with a lot of expense and work. Still didn't work. I found the problem is the regulator has a 1/4" nipple connection to the hose and that's the problem and the choke point. This setup also would not break free an anode out of a water heater. I solved both problems by purchasing a Tekton 3/4" drive x 40" long breaker bar. I'm thinking about switching back to the 3/8" hose since the 1/2" is very heavy to drag around and work with and it didn't seem to make much difference. I wasted my money, but hey, it was a shot.

[@ASC-HELMOND9921]

Great video, I'm also interested in the torque tester you use. Is there a video how you build it?

I have a CP 721? 1/2” that I bought in 1990 when I was working at the John Deere, Steiger dealership. No, it is not the Central Pneumatic! It is a Chicago Pneumatic with the numbers stamped in to a metal tag, riveted to the wrench. The reason that I am not sure of the model number is dings from years of use, a lot of abuse, and torquing out of my grip. Every year to 2 years I put in a rebuild kit from CP. This 1/2” air wrench will take off 50% of the Budd or piloted rims on semis that have not been put on by a 1” wrench and someone who loves to pull the trigger. What I do is unscrew the whip hose, screw the 3/8” by 50’ hose to the wrench. So now it comes out of the compressor though a 1/2” ball valve, to my 3/8” x 50’ air hose, to my wrench. It is amazing how much the old air wrenches preform without the restriction of the quick coupler! A lot of guys use to use the long Lincoln quick couplers, I took each of their male tips, put a drill bit down it to measure the ID of the tip. Some common quick couplers are not even 3/16”! Just like the 3/8” vs 1/4” air hose! Another good tip on an impact wrench is to put on a 3/8” by 6’ whip hose, it has nothing to do with stopping the vibration from the quick couplers, it is a reserve of unrestricted air next to your impact wrench. I think that is why your 3/8” test climbs faster than your 1/4” test. Then they tend to flatline because of the restrictions of the 2 quick couplers. When I was at the JD-Steiger dealership, they had an old 5/8” air wrench that would out do some new 3/4” pistol grip air wrenches. But it used A LOT of air, shop law was you had to have leather gloves on to use the 5/8” wrench! It would twist right out of your hands, if you did not know how to hold it. The shop foreman went down and bought my same 1/2”, and 3/4” Chicago Pneumatic air wrenches for his service van after using mine. Check out the ID of your male air quick couplers, remove the quick couplers from the compressor, get rid of the hose reels, install a 6 foot whip hose on your impact wrench. You will probably be surprised by how much power that your impact wrench has!!! Hello from north east Montana. 10 miles from the Canadian border.

[@998RC]

If you used a 3/8" hose with 3/8" fittings, would you get the same results as the 1/2" hose with 3/8" fittings, since the 1/4" NPT fittings are the weakest link (which you explained in your triple air hose video)?

[@RC.56]

I don’t get it, but 30 gallon compressor, two 50ft 3/8 lines, And all the fittings on the lines are 1/4inch npt. Will be using for painting, HVLP guns. Shouldn’t I get 3/8 line with 3/8 fittings? Why does standard mostly come with quarter inch fittings on those 3/8 lines?? Lost

[@potterma63]

I've got a Chicago Pneumatic 1/2" drive that wouldn't even run on 1/4". Had to re-plumb my cheap (C-H) compressor to 1/2" (tank plumbing and hose) to 1/2".

[@maubunky1]

Can somebody test their Blubird hose, by putting a 5/16" drill bit inside the brass fitting that comes pre-attached to this KZbin channel's most recommended hose...the Blubird 3/8 I.D. hose? My Made in the USA tekton hose that is highly rated has an I.D. rating of 3/8, but what is the point of that when the pre-installed brass fittings at the end only comfortably fit a 1/4 inch drill bit size (it necks down so much right after the threads). I don't see the Blubird hose sold locally for me to go and test this out, and only one person on Amazon is just guessing that the Blubird 3/8 hose has a 5/16" hole in the fitting where it necks down.

[@ldnwholesale8552]

1/4" hose? Never. I used to use 5/16 which was just ok. That decades ago pre rattle guns. I have used 3/8 generally ever since. I tried 1/2 to the gun but just too awkward. So use 1/2 to the 'points and a 30 foot 3/8 from there. Since recently buying a new compressor which pumps 125psi the gun feels a lot more spritely than the old 100-105psi. Though having battery tools now the air tools dont see a great deal of use. I have used Ryco fittings though may change to Nitto as they reputedly flow more air. And hiss less as well.

[@aaronbritt2025]

Guy at my shop tried to tell me my IR 3/4" gun sucked because it was hitting only as hard as his 1/2" gun. I had to spend 15 minutes explaining that if you run it off a 3/8" line instead of a 1/2" (or 3/4", like I use to), it won't hit that hard. He was having a hard time removing a cross threaded lug nut. I hooked it up to my 1/2" line and instantly snapped off the stud. I said, "you're welcome" and walked away.

[@hardeho]

I was wondering why my new 450 ft/lb air impact was struggling, and now I realize, that its because I bought some cheap ass black Friday special 1/4" 100 foot line, because I didn't know the difference or understand pneumatics at all.

[@goldcountryruss7035]

Hose size is way more important when feeding a high speed rotary tool like a grinder. Low air flow and pressure kills both torque and RPM. My 1/2" air drill is a beast that chews up stainless steel with a good air but a long 75' or 100' 3/8 hose and 3 or 4 couplers make it near useless. Same goes for almost any die grinder. Under the same conditions either of my old 1/3" impacts work OK, not great.

[@silentferret1049]

I think 1/4 inch is for air sprayers and even light air tools like nibblers. Never recommend anyone use a 1/4 inch outside of that. Maybe airing up tires but even then it depends on the tire.

[@DEHOYOS98]

We use 100' of ¼ on our compressors airing up monster truck tires and it absolutely sucks! Getting from flat to 18psi takes 10-15 minutes, even with a 5.3 cfm compressor.. But dragging around that much ⅜ hose just isn't doable. I actually just ordered 50' of 5/16" hose to save a little time.

[@TheSatch10]

Sweet video dude. I just bought a new hose and set of fittings because of this. Have you tested the Ingersoll 2235TiMax yet?

[@TorqueTestChannel]

Not yet! Will be soon

[@mccarterjg]

I sincerely didn't think that only 25 for the hose would be enough to make a difference on half inch and 3/8

[@Drundel]

I'm glad you put in the IR with 3/8 vs SMA with 1/4. That really drives home the point on improvement over the years.

[@maxpower9848]

Why would anybody still be using air tools? I went all electric about 2 years ago and I'm way behind. No more compressor no more extension cord no more air hoses and way more power. It's fantastic! Maya Milwaukee heavy duty impact has 1200 foot-pounds of reverse toruqe!
