Does Size Matter? Milton Hi-Flow Air Fittings 

Great vid! Thanks for all the links and part number!

I converted my entire shop to Milton V-Style (High Flow) fittings and couplers and never looked back - they are great

Great, to the point video. Very informative. No music or filler. Thank you.

Dude! right on! because I was so confused when I got my new Flexzilla 3/8 air hose...did not think about the fittings to go on it..thanks again..

Love the Milton high flow!!!

I enjoyed your video. It was very helpful. Thank you!

Lol. You're having too much fun putting that plug in that fitting!

Home Depot sells some nice high flow fittings in a kit. For high flow fittings to benefit your tools you have to replace all of them all the way to your compressor. They make a huge difference in the power of your tools.

I just got Milton connectors , some OEM Hi flow and some Flexzilla hi flow . The inner diameter of the OEMtools and the Milton were 0.259" , the Flexzilla inner diameter was 0.291" . Visibly larger, which prompted me to get out the calipers and measure it. I'm running 1/2" Flexzilla hose with 3/8 ends and Flexzilla High Output connectors on the ends . I run this for my auto air tools ...I run standard connectors for everything else, nail guns, staplers, brad guns with no prob .

Thank you....great advice.

When it comes to specifically moving air, or volume (CFM) dont forget that cfm is decided by the smallest size restriction in the air line system. So along with high flow quick connect fittings you also need a matching air line/hose. A 3/8" air hose works well with the Milton high flow fittings but BE SURE the end fittings on the hose are also high flow. Many are not, and have an inside diameter of 1/4". This is particularly important in the performance of a media blasting cabinet and an HVLP paint spraying gun, where both perform best using high volume.

Thanks for the info, but please turn the volume down on the music - I have ear phones on and just about ruined me.

I bought some of them Milton high flow fittings and they work great with everything except lowes standard fittings Automotive. when I insert them it just leaks like a SIV and it is leaking where it connects to one another

One of my pet peeves is buying airhose of a given diameter and the treads are a size smaller, I but a 1/2 hose I want 1/2 threads on end of the hose

I like the flow of the v style but the couplers did not hold up and began to leak and stick. I have moved to Prevost S1 couplers. They are compatible with the V style plugs Prevost guarantees them for 3 years if you buy their plugs also which my distributor carries and will warranty. I have also used the Coilhose universal which works with the v style plugs.

Excellent video and thanks for posting. My concern about using the high flow fittings is that unless ALL the fittings in the system - from compressor to the tool - have an equally as large (or larger) unrestrictive hole for the air to flow through, there will be minimal or no added CFM through the system. Upgrading to High Flow fittings may not be enough. I'm looking for a hose reel and am concerned that the air passages in the rotating swivel fitting will be restrictive and limit the CFMs through into the 3/8 hose on the reel - and downstream . I asked the question directly to Milton about the diameter of the air passage hole(s) in the rotating fitting they use and how it compares to their purple V-series High Flow Pro fittings. They did not answer my question. I saw your excellent review video of their 3/8 x 50 foot hose reel and was considering it, but I'm holding off. I suspect that regulators, ball valves, swivel fittings, hose barbs, couplers and plugs are all potential log jams in the air train. Of course, the length of the run and all the twists and bends adds resistance to the air flow. It would be interesting to dissect a typical system and look at the actual flow diameters of the various components to reveal the hidden restrictions. I'll subscribe to your excellent channel.

I have been designing compressed air distribution systems for several years now and offer free tips on upgrading your shop air. it all begins at the compressor intake filter

Thanks for taking the time to make this video man. I’ve been in the automotive repair trade for 14 years, only found out about this recently. I’ve replaced all 30 of my air tools with these fittings. Difference is night and day. Power mode unlocked !!

Type G is 1/2 inch. The Mandingo of pneumatic couplers.

I cannot get the hose and moisture trap to stop leaking air. Only tried Teflon tape so far though

Thanks for the video. I'm currently shopping to graduate from my little pancake comp to a grownup compressor and came across these. Exactly the info I was looking for. One question: I'm probably going to get a Rolair VT25BIG which claims to have 2 x 1/4" quick connects (which I'll be connecting to a 3/8" x 50' hose on reel). Will these cancel out any benefits the NPT V's would give me? The connects are Rolair parts (VT447013).

What size hoses do you use? Specifically, what size is your flexila hose. I've been told the hose diameter also affects the airflow. You agree?

So, what about Hi-Flo vs 3/8? It’s ever so bigger. 7.62MM VS 7.89. Is that enough of a difference to warrant the changeover? I already bought them but did not realize how little difference there is.

Wow... @ 03:47 I can't believe that went on with one hand.. I have to struggle with mine and that's getting really old, fast! Also I have one female with a big fat release collar that's amazingly easy to disconnect.. my new coupler's are such a struggle releasing.. looking for a better solution!

What and where did you that grey block that was connected to your main air feed supply line?

Use the Teflon sealer over the tape. A little tape can break off and get stuck in a tool.

Watch it this way 0:04 0:54 1:28 1:40 4:40

Can your 15 gallon tank do the same as your 60 gallon tank using the hi flow fittings since the 15 gallon tank has a 1/4 inch outlet welded to the tank ? Fill a tire with the 15 gallon timed and one off the 60 gallon tank timed .

Another thing, all 3/8" air hose stock fittings are not the same I.D., some are larger and some are smaller and these measurements are never given online when you're buying a hose. I just returned a 3/8" flex type hose to Amazon because my 10 year old Goodyear 3/8" hose had fittings with a larger I.D.

I have 1/4" 100' hoses and twin tank 4gal compressor. I find it that when in framing with my framing gun it leaves the nails proud. Do i change the hose to 3/8 or do i just change the fittings as well.

I'm trying to buy a 3/8 hose. Now my question is, most of the 3/8 hoses I see come with 1/4 NPT ends. Does that mean the hole is 1/4 or is that just for the threads? Or am I supposed to take those off and put 3/8 fittings? I'm a little confused.

So I wouldn't have to replace my connecters just the fittings

Can I replace JUST the Male fittings on my air tools with the Milton high-flow and leave the regular fittings on the air hoses? I work in an auto shop and don't want to replace every coupler on the air hoses with my own money and not have other employees air tools not work because of the high-flow.

Do you know if there are any high flow swivel fittings?

Do I have to replace the quick connectors on my compressor too? If I stick with 1/4 inch will i get an increase in performance?

i am interested in the wall adapter where did you get it .

Which do you get more performance out of, running 3/8" high flow fittings with a 3/8" hose or 1/2" hose?

But if you look inside the fittings on the air hose that you screw the female fitting to they are just as small as the stuff your replacing. So you might as well chop those off and get some hose clamps and put high flow fittings in the hose ends to. That's what I'm doing

What’s the brand name and model of the wall mounted manifold?

What was the thing you used on the fitting in the can?

Reducing restrictions anywhere increases air flow. Every restriction ads up. Easiest way is to crank up the air pressure not to exceed any part of the systems safe working limit. I know these people own a truck salvage (junk) yard. I watched him take off a pinion U joint yolk 2 1/2" socket with a 1/2" automotive air gun. I said how much pressure are you running he said 160 PSI I said you know you're only supposed to run 90 PSI on air tools. He said this gets the job done, when it breaks I'll get a new one. The big truck leaf spring and suspension repair shop I went to can repair a wore out suspension while you wait. You out to hear those air guns going all day. They buy air guns 20 at a time kept in the tool room. Penny saved is a dollar lost.

حلووووو

Yes it does just ask her...If she says no...you know where you fit in. She's trying to be nice to you LOL

Just did mine today $220.00 bucks now that sucks.

His 1/2 ok

Damn, turn down the intro music, please.

Well, I'm going to have to call you out on where the male and female are used. My pressure pot requires a female fitting, my blow gun also requires the female. So you're wrong on that part, and no I'm not adding a coupler to the $350.00 pot to put a male fitting on it, more bullshit. My tire inflator and my $250.00 BeA stapler also takes a female fitting, other air tools take the male fitting.

Larger couplings = the compressor running out of air sooner.

Them is some expensive fittings!

G style or nothing!

Joe Biden would run add on a size matters video. Creepy old man! Thanks for the tip. Lol

Total BS and hype. A simple flow meter will tell you you get at most a 10% increase which is useless because you are already getting more CFM than you need with M style couplers. Hilarious how stupid the public really is. They can sell you anything.

How do you know what gender these fittings identify as?😲🤣🤣🤣🤣🤣🤣

I enjoyed your video. It was very helpful. Thank you!
