An expansion tank would/should work better if you're already starved for air like a small compressor or super far from the source. Just didn't quite do what we needed to test 3/4" impacts faithfully. We've also been compiling for over a year "conspiracy theory" sort of techniques from the comment section you guys say increase torque from impacts. Like holding the socket or turning in the direction of impacting. We have like 9 or 10. Share your tricks of the trade for us to test in the future when we do that! NOTICE: I came up with the original version/prototype of the 3-way air swivel, so while none of us benefit financially from it selling, it might not come as a surprise that A) we like it and B) it does well on the tools we test with. Always consider multiple sources when looking at a tool!

That's what I do in my home shop. I have a higher-end but still home gamer 120v Husky compressor with a 4-gallon 225 PSI internal tank piped through a regulator to a pair of 155 PSI 10 gallon portable tanks and it nearly triples the amount of time I can run a die grinder before the compressor drops below a reasonable 80-90 PSI to it's steady state flow of around 50 PSI.

WOOOWWW I am literally parked in harbor freight parking lot, and having finished a previous video right as I was pulling in, this one started auto playing. I stunned by this because I am at harbor freight to get air fittings for a couple tools and was trying to remember and decide which fittings style/size are best to truly optimize my pneumatic tool setup as well as contemplating whether or not to get an in line filter or any other piece of gear I would need for my tools. Then what do you know, the absolute perfection of a video going over exactly what is the best and why comes on and I gotta thank you a ton for doing what you do to providing truly priceless, eductional, and humble data for all us consumers.

[@jacobkarns2025]

An old timer showed me the trick of running a short air hose whip off of all my tools when I was working at the truck dealership. That keeps you from denting fittings of you drop the tool, it also helps prevent the fitings from cracking in your air impact/hammer tools.

[@afullgrownchild2402]

I've got the ported Thor with the same 3/8 big chungus fitting you got in a diesel shop. We run 150 psi through 1/2 for our big tools.

[@gwall1789]

Been using 1/2” hose and Milton P fittings for decades. Gonna have to pick up some of those Astro swivels. Keep up the good work.

[@crazyfvck]

For years and years, I used M-style 1/4" couplers with 3/8" hose at home, just like my dad did. I never gave much thought to the restrictive fittings. Then, in my early 20's, I became a tech with a company that started doing NADCA-Certified duct cleaning, and over time, I kept finding ways to improve the equipment we used. They were using the same setup that I did at home, which was 1/4" fittings on 3/8" hoses (though the compressors used were putting out higher pressure, between 150psi and 175psi.) I noticed the restriction in the fittings one day while setting up a new trailer, and decided that it was probably not helping us. I switched them out for higher flow 3/8" fittings that I found at Home Depot, and the difference was crazy. I also added an expansion tank made out of a cheap Harbor Freight sandblasting tank, and that also made quite an improvement in all of our Nikro air whips, blow guns, etc. After I left that company, I moved into a new house, and started deciding what to do about my air compressor and line setup. I soon discovered 1/2" air hoses, followed by Milton G-style 1/2" NPT fittings and couplers, and I knew what I was going to use! The flow is AMAZING! I do have to use reducer bushings on almost every tool, but that is a small price to pay. Now the only restrictions in the system are right by the tools, and I doubt it makes much of a difference.

[@jimsvideos7201]

The point of a buffer tank is to have whatever you have in the shop feeding it, but a short piece of the biggest hose you can live with plumbed into the tool with a non-restrictive swivel. It's only useful for high-draw tools.

[@shawno8253]

If im understanding this right a buffer tank just increases the volume of compressed air available. Which if thats the case why not just get a bigger air compressor?

[@whyiseverythingonfireagain1190]

​@@shawno8253a tank can make up for long lines. I really wish they would redo that test in a way more like you would use it in your shop. For example I might have 50 ft of 3/8 from my regulator to my tool. If I connect a buffer tank to the end of that line, and then 10ft of 1/2 or even 3/8 I should see much better performance at the tool for a couple seconds. Need a Dyno to prove it tho hint hint

[@sixtyfiveford]

Great demo. FYI don't get tempted by off brand Milton V styles. They have horribly designed female couplers that are extremely restrictive and you'll lose air flow. The male are about the same though some off brands have a significantly smaller center hole vs the actual Milton

[@richardwernst]

I was hoping for a summary in the info section, with suggestions for home shop (20-30 gallon tanks, 125psi) and home type tools. I think what I'd like would be to change the fittings on my 3/8" hose so it'll take larger quick connects, etc. so I get essentially 3/8" flow throughout. And to add to a followup, it would be interesting to see if longer runs of hose make much of a difference, ideally with just couplers at the hose fittings so other than turbulence there, no restriction.

[@JCcanU]

Save your Money the Tank only has a 1/4 outlet adding larger hose is not going to boost anything but your Pocket book . Save up get a 60 gallon tank with a 3/4 outlet . 20 CFM , 6-8 CFM is not going to matter with a 1/4 inch tank still be 6-8 cfm .

[@oby-1607]

Milton V is the only thing we use for quick connect but if there is a real need for torque such as taking apart large rusted nuts and bolts then 1/2 inch air line hooked up directly to the hi-torque 3/4 air gun gets the nod. The hi-torque Milwaukee won't touch these bolts but the 3/4 air direct doesn't even feel them. Pressure is supplied by a measly 5 horsepower gas compressor filling a 200 gallon repurposed propane tank.

[@ASK13saregreat]

These are all things what I have wanted to see and wondered about! Would TTC ever be interested in doing an episode about hose reel losses? I used a 3/4in 2ft hose right threaded into a 1/2 in hose reel from the compressor then 3/8 hose on the reel with high flow V steel fittings. Was pretty cheap. I'd love to see a high flow astro hose reel.

[@bcekli]

Milton V seems to be the ticket. Especially since they can still accept M style as well. Great video! I still would love to see the difference adding an air tank makes to a simple 120v compressor most have at home.

[@ColdRiverAutowire]

Built my air system around Milton V, no regrets at all

[@MD-gk4uh]

THIS! Most of us have 120V 10-30 gal tanks. I feel that's where people are the most "desperste" to get more hitting power. At work I can run my gun non stop (huge industrial compressor) and min later the "stuck" bolt is loose even on 100psi max. At home I only have 10gal 130 psi and if the bolt doesn't move in first 5 sec the power curve is dead and I have to wait 5min for compressor to catch up. Also you cant run those non stop and after 3rd run it will take 10+ min to fill and be so hot i have to stop for 30min. Removing a bolt that needs even full 15 sec of hammering is a pain...1 min completly out of question unless you want to spend the afternoon on it.

Your DP commentary never gets old. I would like some more DP. BTW I use the flexzilla on my air hungry tools that need the swivel. Been pretty happy with it for the last ~2 years. I use some HF fittings made of brass I got off Amazon. They seem to hold up fine Been ~3 years without issue.

[@MrNside]

The aux tank will likely only work for smaller tank compressors. I use that same harbor freight tank with a 6-gallon pancake compressor for nail guns, and get noticeably more CFM and/or time between cycles.

[@TorqueTestChannel]

Makes sense, I do the same at home with a separate slave compressor that doesnt turn on.

[@MrNside]

@@TorqueTestChannel I put a regulator on the aux tank too, and just keep the compressor at 125 PSI (aux tank max) and as far away as possible so I don't have to listen to it. Then just regulate for the tool after the AUX tank so it's still pressurized at 125.

[@MrNside]

@@jsplasha for a shop set up, a dryer and oiler system would be great. Mine is mobile though, and I don't always use the aux tank. I usually only break the aux tank out when I need to run guns for multiple people or when I am working inside with larger CFM nailers (framing, cleat) and I want to leave the loud AF compressor outside, but still be able to adjust the pressure near where I'm working. I have a smaller quieter compressor for trim nailers that I take indoors otherwise.

[@MrNside]

@@1pcfred For my particular usage, the CFM isn't as much a benefit as the added capacity. Nail guns don't need a ton of CFM as long as the pressure is there. The closest I have had to an issue using my 6 gallon pancake with an 11 gallon aux tank is when I ran 2 roofing nailers off of it, and the two roofers using it were both on straight runs of roof simultaneously. Compressor was running more often than it wasn't. That was about 7 years ago on my then 10-ish year old pancake. I still use that compressor pretty often.

[@KaylaJoyGunn]

Same, got a 15 gallon compressor, hooked up that same yellow 11 gal tank as a backup. Ran it all in 1/2 hose with a 3/4 earthquake impact in a desparate attempt to get out a honda crankshaft bolt, but in the end, the best psi comes from an oxy-acetylene torch 😂

I did a lot of research and switched to Milton V fittings 4 years ago. I like them because they are compatible with the industrial kind (applications where peak airflow doesn't really matter). They seem to take a lot of force to plug in though. I always wondered if the T fittings were easier. Doesn't matter. I have a tiny air tank (12 gal) and the only thing I even use it for is inflating tires and blowing air. I am in the market for a power ratchet though so I may want to think about air vs battery. For impact, I'm quite happy with cordless.

[@obfuscated3090]

I'd go cordless for the ratchet. I have several pneumatic ratchets and haven't even used some of them (I bought them with a loaded rollaround). OTOH cordless tools are far more mobile and I take mine into salvage yards, all over my property and elsewhere.

[@thomaspolley4977]

I would like to see a video comparing regulators. I did a little bit of research awhile back and a few people said that the biggest air flow restriction is the regulator that comes with most prosumer air compressors. I plan to install a tee coming directly off my tank, and run it to a larger regulator. That way I can keep the pressure switch and factory regulator intact.

[@Comm0ut]

If you want better flow just plumb a chuck straight from the tank and skip the regulator. The only reason to want a regulator is to lower pressure for special uses like spray painting, light blow gun work etc and where applicable OSHA blow gun compliance.

[@70stastic]

Lol, my air setup has 3 of those HF 11gal air tanks as an additional volume boost. It works great. I also have 2 110v air compressors along with it and it'll maintain 90psi all day at my sandblaster. It's the cheapest way I could find to get high volume air at my shop.

[@lachlanhatcher9108]

On the topic of the for science videos, how about running the air tools on way more air pressure, like 3000psi. I've was really interested in finding out what happened so I did some tests myself with a pneumatic cut off tool (without the cut off wheel on) hooked up to a repurposed CO2 fire extinguisher running 3000psi from it into the tool. It didn't blow up but just revved extremely fast and felt like it had loosened up a bit after but was otherwise undamaged. An impact wrench might be a bit different and idk if the trigger would be able to stop the push of 3000psi, but if it could I'm sure you could get some crazy power out of it before it blows up.

I have 2 compressors both hooked to piping that goes through the shop, out to the driveway, and up to the top of the basement stairs. One is about a 60 gallon PAR from the 1930s with a 3 phase 3hp motor, pressure switch at 160 psi. Inline twin cylinder pump running at around 750 rpm. The other is a V twin 1940s Craftsman with 240v single phase 1hp motor but no tank. It comes on when the pressure in the piping reaches 95 psi and shuts off at 125. I use 1/2 inch G style couplers for big tools, 3/8 T style for everything else. With a 1/2 inch old style aluminum Earthquake impact running at full blast, once the Craftsman kicks on, it just stays at 95 psi, it won't drop below that on anything other than the big rotary sander or a big blow gun on a half inch hose. Compressors are hooked up to the piping with 1/2 hydraulic hose and Chicago fittings. The original plan was to get a second tank for the Craftsman but I have yet to run into a situation where it's necessary.

[@cccspokesmanandcofounder]

[@ForfeMac]

When I worked in a big diesel shop, we had 1" copper pipe run down to every work station, and our air compressor was a massive 3 phase screw compressor that put out multiple hundred CFM of air at ~220 psi. It was nice having a virtually infinite amount of air on tap, sorely missed in my new shop. Then again, it's not too often I need to break out the #5 spline gun any more, so I guess it's worth it. Also, electric tools are way cheaper to run, which is important when you're the one paying the utility bills.

What would be interesting with these tools tests is to measure the air pressure right at the gun itself. This would give you hard data about airflow but possibly also that the tool is maxed out in terms of power output. So comparing air pressure versus power out right from the gun or tool. The thicker air hose to me is thicker wire, lower resistance and higher current flow or air flow. The nozzles basically do the same thing, they are connections which can impede or slow down air flow. But the key point to me is the instantaneous air pressure right before the tool. If you wanted to entertain a crazy idea, put a tiny little tank for air right at the tool itself to see if the tool suffers from capacitance or lack of instantaneous air pressure or inductance or lack of instantaneous air flow. All that aside, I love everything you guys do on the channel!

I did the exact expansion tank trick years back to help out my crappy 30 gallon oiless Craftsman compressor. I just tee’d the opening of an identical Hazard Freight yellow 11 gallon too. Always figured I would buy another weld in 1/2” NPT bung and weld it onto the other side of the tank. Figured the turbulence has to be wild and restrictive using the tee method. I bought cordless stuff and the compressor barely comes on anymore. Never got around to it.

Great video! I'd love to see "Euro" fittings (PCL XF) added to the comparison, as they're what we use in the UK, as well as Japanese Industrial Profile that Japanese tools come with. Of course with these you're changing both sides of the connection, so a trickier comparison.

[@tomcardale5596]

Yes, I'd love to see this. Or even a measurement of the fittings used so I can see how they compare with PCL fittings. I have the PCL Standard on all my air tools. No technical reason, it was just all the tools I'd ever used were PCL so that's what I standardised on.

[@Adam-bw4lw]

The best mod that i did was to remove the 1/2 plug from my air tank and spin in a 1/2quick conect fiting with a 10mm hose straight to the power tool 😀

[@deankruse8751]

I was really hoping to see a large 3/4 or 1 inch air hose choked down to a common 1/4 fitting. I have heard so many people try to say that it increases air flow because the hose is bigger. They don't believe me when I try to explain the weakest link idea and that if any part of the system is restricting the flow then you don't gain anything from the larger hose

[@dorsetengineering]

Very interesting…. If you ever revisit this, I’d be happy to send you a bunch of the fittings we use in the UK to see how they compare. We have typically two styles - PCL and Euro….

I got the flexilla high flow on Amazon, got the big wall hanger kit with some of everything it’s worked great for me as a home gamer maintaining my truck and trailer.

[@volvo09]

Damn! That was a lot of testing!

[@briankleinschmidt3664]

I'll keep this in mind for when I need to torque a nut down to 4000 psi. Or when I'm ready to wreck my impact.

[@jonathancorbett5917]

The 3/8 couplers are steel and can be "ported" and won't dent under normal use. Try adding a second regulator or larger regulator to see if the buffer tank is necessary

[@beyblayder]

Man, I'd love to get one of those 3/4 thor impacts.

[@boltonky]

Great testing, sometimes i wish i lived in the US where things were cheaper and more available. Generally our compressors go from (single phase) -16cfm (big diy/small workshop 100L) straight to 3 phase 42cfm workshop one 300l tank with nothing in between so airline sizes + expansion tanks make a huge difference to nominal output & we all know its actually about free air delivery not rated cfm. There is a lot of maths that goes into doing setups correctly...enough of me keep it up and thakns

[@jozsefizsak]

Fascinating.

[@ChrisMuncy]

Another coffee and TTC morning! Thanks! BTW - got any plans for another Q&A?

[@thelightaddict80k]

I use two hoses into on for blowing the shop out works so well especially if it's 2-1/2 inch lines

[@metricstormtrooper]

The thing I found was improved by a buffer tank was a high capacity nail gun, the remote tank allowed me to nail into tasmanian oak with 100mm nails on an elevated two story house where it was impossible to put the compressor on the top floor.

[@TandD1w]

As much as I hate them, I now feel justified using twist-lok fittings on my 1/2" hoses.

[@GearheadOutlaw]

YES. Thanks man

[@stevemiller6766]

The tank would work fine at the end of a long line with short tool usage times to allow a recharge. I think the tank would be better used for air nailers. Have you tried to measure the air flow to these tools? Would be interested to see which tools are more efficient in terms of air usage vs power. Thank you for very informative and entertaining material guys!

[@dontdowhatido6503]

this is like tuning engines but with tools instead. SOO SICK. you should try to see what is max torque it can make. as in pushing like 400psi through it

[@jameswieler3295]

Thanks, awesome channel I bought a Thor because of you. Question: what about the fittings on the regulator? Should those be using 3/8" or 1/2" when using a 1/2" hose? Also, have you tested Milton G-type fittings?

[@ONeal397]

I NEED that 3/4 Thor

[@slickrick343]

Over here in the UK most workshops seem to use a 1/4 bsp fitting. I have no idea why as I assume they choke most tools. And you even get Milton style fitting provided with most tools you buy. I've got loads of them in my box sat unused.
