My 2 cents- If you're just starting out buy 3/8" high flow hose with 1/4" high flow fittings. 3/8" is the internal diameter (ID) of the hose, and 1/4" is the size of the thread on the fitting ends, NOT the ID. The high flow fittings still have 1/4" threads but their internal diameter is larger, which means they flow more (CFM). This can come in handy with an impact wrench on a stuck/frozen nut or for some spray painting guns. Milton V series fittings are high flow, and they also dont require you to pull back the sleeve on the quick disconnect fitting to connect. Just push. Only releasing the hose fitting requires pulling back the sleeve. Also, you can buy repair fittings for the hose that dont require a hose clamp. They look almost like a factory end. Last, Makita makes a nice 3/8" air hose that has no coil memory. It curls in either direction with no problem. I am sure there are others out there as well.

Never thought I would be watching a 20 minute video about air hoses and not regret it. Amazing video, it told me everything I needed to know. Way to youtube.

Thank for the time it took you to explain this this in-depth to newbies like myself. Evan the different type of compressors available. Real work guy Thanks.

I want to thank you for your detailed instructions on connecting the hose. I am a newbie and I needed air in my tires. I was not able to keep it connected. I watched two other videos before I saw yours and finally I was able to connect that darn hose to the fitting. Thank you so much you are awesome. Great visual aid in assisting those of us that have no clue. You saved me cause I really needed air in my tires.

Thorough and exhaustive, thanks for sharing the knowledge!

I'm completely new and lost to air compressors! This is one of the most informing video I've seen. I feel so much better "kitting out" my first air compressor. Thank you for sharing!

This vid saved my life. I’m getting into casting my own sculptures but I’m utterly shop tool illiterate. I was confused as to why my hose fittings had so much space and my compressor just leaked air, i had no clue about sealing tape. Thanks for the patiently described and extremely informative video!!!

Just came accross your video and must say it was very informative! Especially appreciate the fact that it is coming from someone with years of actual experience and expert knowledge to back it up! Thanks!

Really useful video. Perfect for me as a beginner in this field. Thank you and greetings from Portugal.

Love your voice. Thanks for clearing up the connection confusion I had.

Thank you for such a thorough video! I feel a lot more confident in choosing the right hose/fittings for me now.

Very informative and helpful, had no idea what hose to buy for my new pancake that was given to me. Thank you.

Thank God a real educational video about air compressors, the hoses, air connectors, and tools. The sheer amount of clickbait with referral links is frustrating that youtube has been paid to suggest is frustrating. Thank you for taking the time to make an education video for the benefit of the masses. Paying your knowledge forward and leaving pieces of yourself and your knowledge in over 113,000 thousand people. A living legacy to be proud of off, although you come off as humble person.

Thanks for all the great info. In the many times over the years I've used compressors, I never realized how much I didn't know until I went to buy my own, lol.

Thank you so much for sharing all this great information!

Awesome video. Thank for the excellent info and especially for cutting to the chase AND not having music!!

Good explanation video. I had to watch 3 videos before I got to yours that answered my questions.I've used compressors but I have never purchased on and needed to understand what to use and how to assemble the fittings. Thanks for making it easy to understand.

thank you! great information. thanks for taking the time to help so many people.

This video answered my questions about fittings, hoses and size. Very informative, thank you.

Great video. I also have a tip if you have a long distance between the compressor and the job, I use a seperate 10 liter tank close by the job. So run a 40ft 3/8" from the compressor to the extra tank and from the extra tank to the tool. It really works well for short burst of full pressure tools. Ofcourse not for long periods then your long hose will become the weakest link again.

Sir, you are a master!! Great video!!

Thanks for explaining it's so confusing lol. Cheers Tim from Wood 4 Nothing

Excellent information in your video! Thank you.

Great informative video, thank you for sharing your knowledge :)

Thank you for such an information rich video a on hoses and connectors! Very valuable to me as a newbie.

Thanks SO much for making this video. I’m a first time home buyer, and a first time user of an air compressor system, and I was getting really confused on what to buy, the names of all the fittings, etc. This video answered a bunch of my questions.

Learned a ton from this video -- thank you

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

ohhh I needed this explanation so badly - thank you!

love the last part , "the trick". valuable tip from the pro.

Comprehensive and very informative. Thank you for sharing your experience and expertise. Its a big help. God bless.

Very thorough! Good teacher

Just the video I was looking for. Thank you for the info.

Great video, love the joining of 2 compressors at the end of video. I'll do that...

Very detailed and informative. Thank you sir.

Thanks this helped so much!!!

Thanks for the video! Very helpful!

Thanks for the best information I've seen so far. 👌 very helpful.

Excellent presentation and a great teacher 👍🙏

Thank you sir for this information!

When threading fittings with teflon (plumber's tape), wrap it clockwise so it doesn't come undone when you screw on the fitting.

Thanks. Very informative to a newbee

Thank you, very well done and informative presentation. Keep up the good work!

Good recomendations thanks it really helped me 🙏

great video! Thank you so much!

Thanks, really helpful!

You saved my day! Thank you very munch!

U don't want to over tighten. Don't crank it down. Good video bro. Keep em coming

4 years later and as relevant as it ever was. Good to hang out with folks, center a discussion around a topic, trade tips and learn. My tip is to get a larger hose for next to the compressor, then hook lighter ones for added distance, if you need to. That big hose is a reservoir of air, once filled it extends your tank a little, run anything a bit longer. And, it takes some of the wear. You could use 3/8" or even 1/2" at the tank, and adapt down to the extensions' size. You should own hoses of different types and sizes, especially if your work and location can vary!

Great tutorial and tips.Thanks a million!

This is very helpful, explaining the differences. I wish I saw this, before I bought my air hoses, and fittings. Now I will know what to replace them with, when the time comes. I use a tank that has no compressor, the kind you fill up with a gas station tire filling air pump. I use that as an extra capacity tank, connected to my small compressor. What I have noticed is, that you get more use between, when the compressor runs, but the compressor runs longer, each time it refills the tanks. Not sure what the value of that is.

Very good explanations, Thanks

Thank you, clear and precise and for a newbie like me, perfect. Love the hack to for more air. Brilliant.

Roofer here!! we always use rubber hoses, never needed polueurethane, u stuff the extra hose in the peak then run back to where you're shingling so it doesnt pull the gun down for that forth nail

Thank you so much for 3:09 I’m tryna put air in my dad tire before he gets home 🤣😂

Thanks. This is very helpful. I purchased a dually and had no clue how to get from the compressor the the air head.

Great tip on ganging the tanks of multiple compressors. Never thought of that.

Excellent video. Thanks for taking the time and effort to create it for the rest of us. Joe Pesci and you share a similar sounding voice btw. You could do voice overs for him lol. Anyhow, thanks, man, for such an informative video. Peace.

Great video!

I wish to heck I had found this video first, you would have saved me hours of research. I had to replace our old home compressor, and I knew zero about them. Starting from zero knowledge, I managed to learn enough about them to choose one that was right for me. (I found a Makita 2.6 Gal oil lube that should be perfect) but then the choice of hoses and fittings was another hurdle. Your video laid out in a little under 20 minutes what I needed hours of reading and video watching to accomplish, and some of the stuff you explained I would have never even thought to ask. Many “handy people” discuss things in such a way where they have an assumption of a certain level of knowledge that I did not have, so I was left with many more questions when they were done talking. You explained everything in such a clear way, and answered many questions that always remained after reading and watching other videos. Thank you for taking the time to make this very I formative video.

NICE VIDEO THANK'S FOR THE INFORMATIONS.

Good advice very helpful

Thanks is very clear nd helpful.

I this noob learned allot today. Thank you very much

outstanding video, thanks much for taking the time! Oh, and I 2nd the Joe Pesci voice over comment... :)

When hooking up tanks in series,make sure to open the regulator on the idle compressor or the 2nd tank will not fill with air.

Excellent review.

A big thanks!!

Thanks for sharing that info.. I have a 10 gal compressor and have been trying to get a main shaft pulley bolt off my car but my 3/8 dr impact wont loosen the bolt. I have been told to make direct fittings to the gun and compressor, shorten the air hose to get more air to the gun. Now after watching this video I think I need to go to a 3/8" adapter to my hose. I am using an aircat impact which should have no problem getting that bolt loose. What's your thoughts?

Great Job

Thanks John. I have a pancake compressor now and have been looking for something with a little more capacity for woodworking and finish work mostly. I think you should do a review of that 150psi Porter Cable you use. I'm looking at that one.

I don’t know shit about tools but this was super helpful!

Super helpful, thank you!

Thanks for the info🖒

This is real good info good explanation.

Great info as I am looking at getting a compressor for first time thanks

Info I haven't been able to find anywhere else , THANKS !

Thanks Compressor Professor....

the brown hose that you show the male and female connector to which is not a standard hose most houses are a male end on both ends but what you show is the female connector is a universal connector with three bands it will take either the automotive or the industrial male ends.

Thank you Great lesson lol

The hose 'curl' factor is definitely an issue with the hose that came with my Porter-Cable pancake compressor. I'm constantly fighting it wanting to curl up. I've even considered getting a shorter hose, but maybe I need to get a rubber hose or the hybrid instead. I do like how light the hose I have is, but after using it on my remodel now for a while I'm ready to give up light weight for a hose that I don't have to fight with all the time.

Thank you very much. This was an Excellent review!! Very informative and I learned a lot (exactly what I was looking for). It’s nice of you to take the time and share your knowledge, especially from experience.

Great info

Very informative

Euro couplings are interchangeable with various connectors such as PCL, NPT and hi flo connectors. That makes a lot of sense, what is the point of having lots of incompatible couplers/connectors?

Great vid just what needed. Whats a vertex fitting?

I just came off phone to PCL Co in uk. The vertex is a safety type for trailing hoses. The female fitting has fixed lip with sliding collar. If you knock the end it wont pop apart.

Got to appreciate good hose.

Awesome info! Do you have to treat any of the hoses with protectant to keep the hose from dry rotting or cracking?

I run a detail shop and use a lot of air. No matter which fittings I use they only good for 3 to 4 months, moisture is what kills them, they start to leak. No big deal being I keep several male and female fittings. I'm currently using the 26 gallon Kobalt Quite Compressor with two polyurethane hoses , going on 4 years since I replaced them. Rubber of course are best. Thanks for the video

Great Channel name idea "This Old Hose"

Great video!!!!!!!!!!1

In your demonstration where you inserted the male end hose fitting into the female quick disconnect on your compressor, that female quick disconnect is worn out and leaking. You can easily hear it in the video. The reason is because your female quick disconnect only has three ball bearings in it. If you install A Milton "P" fitting, they use 8 ball bearings and NEVER leak. Back in 1984 I replaced the crappy male and female fittings on all of my rubber air hoses with Milton P fittings. I still have those hoses, and they have never leaked. But the problem with rubber 3/8" hoses is they are heavy and stiff. It is sometimes hard to maneuver an air gun or air tool into proper position. They will however last longer than any other type of hose. I must say though, when I discovered 3/8" POLYURETHANE Air hose that was the end of the rubber hose. Polyurethane air hose is the best thing they ever invented. Super light and flexible, and if you keep it wound on a hose reel it will not kink.

Yooooo I thank you for this video I thought I just wasted my money on the things lost on how to connect the cord to the compressor

7:59 I don't think there's 3/8" "high flow" fittings like there are both standard flow and high flow 1/4" fittings. Milton calls their 1/4" high flows "V" type. They have differing dimensions from 1/4" body connectors other than just the inner diameter, and therefore aren't interchangeable, you have to put a 1/4" high flow plug into a high flow coupler, it won't fit into a regular coupler. The 1/4" high flow connections actually flow a little bit more air than a standard 3/8" fitting, (Milton says 74 CFM for high flow 1/4 and 68 CFM for 3/8) (1/4 regular is only 30-40.) but like I said I've never seen a coupling plug with a 3/8" body with a larger diameter than normal hole through it, just 1/4" ones. Another drawback of larger or higher flow setups are that they can over-use the air and cause the compressor to run more often than necessary. Pages 48 and 49 have diagrams of the different types, their sizes and flowrates.

Thankx

I have one 100 ft PVC hose and the rest are Goodyear black rubber hoses. In cold weather, the PVC hose is stiff, but the rubber hoses are still pretty flexible. In in the SE Texas Gulf Coast area, so our "cold" is not really *that* cold, but the PVC hose is still stiff enough that I avoid using it in our "winter" unless absolutely necessary. Another solution for a larger air tank for your compressor is to adapt a spare 20 lb BBQ propane tank. The propane tank fitting is called "POL" and it's possible to get an adapter that goes from POL to 1/4" MNPT for $8 or less. Once you get to the 1/4" NPT, there are plenty of choices for adapting it to air hose fittings. You basically want a T-connector with one leg going to the compressor, one leg going to the propane tank, and the last leg going to the tool that you are operating. Since the propane tank has a valve on it, you can close the valve when you get through and save the air that is in it, thus not needing to air it back up the next time you use it. Often you can get these tanks for free (or very little cost) because they need to be pressure tested periodically and the tanks are cheap enough that the companies just replace them instead of having them hydostatically tested.

Here’s a hose tip!! Use electrical heat shrink over the crimp holding the plastic crimp saver in place

Nice video! I am new to using an air compressor and bought a100 ft 3/8 hose. I purchased a 1/4 blow gun and tire inflation gun. I have used them and it seems to work, but it sounds like I should switch out for the 3/8 tools instead, right?

So for now and then home use the light hybrid should be best for me, on a ladder from time to time odds and ends etc.? Also will use inside the house maybe?
