problem airbrush troubleshooting - bubbles in the paint cup explained 

Thank you!! Definitely going to buy a self centering now. I’ve already had to buy 2 airbrush with the thread tip 😭.

Absolutely fantastic step by step explanation showing the complete mechanics of problem solving, thanks millions

Amazing - so clear and well explained, not only have I fixed my airbrush, but now I understand how it works 😆- thanks!

Thank you for posting this. I was close to pitching my airbrush (Paasche VL) over this problem.

Thanks for the technical breakdown of how the air and paint channels are supposed to work. That helped me realize i needed to tighten the end cap so that the nozzle was just barely sticking out

I used plumbers tape over the nozzle and that fixed it thanks for pointing these out!

Thanks! Just received airbrush and from start it already was bubbles. I disassembled, reassembled to be snug and fit and now it works as it should!

I can't thank you enough for sharing your knowledge like you do! This video just saved me so much frustration. I'm a newb and trying to absorb as much know how as i go along but still ran into some troubles with my new badger sotar that i only used for a day, now i have to mention the airbrush i had before this was $20 princess auto special that was a nightmare to use.. so seeing the level of detail i can get with my new one i was pretty stoked. So today when i used it i put some primer in it that apparently isn't recommended for a needle as small as the one i have.(should've read the bottle first) It bunged up in there right away and I spent hours messing with it till i found your video. That part at the end where you mention how that tiny lil nozzle tip thingy is supposed to sit. No one else in the multitude of vids on here touched on that point. So much gratitude! Def know where I'll be taking my business next time! cheers

At 11:45 that was my problem, fixed, thank you. I will order a new one for future.

Great Video. I think you just explained why my Iwata stopped working! All I get is air and no paint out of it. Damn those small nozzles.

Thank you!! Literally the first time I cleaned my Harder and Steenbeck I dropped the nylon washer from the nozzle so it leaked from the front 5 disassemblies + this video I found it on the floor next to me. Thank you I wouldn’t have know it was missing without this.

This guy explained it in detail very helpfull yo understand how airbrush works

Video helped a lot. Had been plenty of places looking for my bubbling into my pot problem but you are you only one I'd seen who laid it out so a newbie like me could immediately see I had damaged my nozzle and that it needed replacement! Thanks so much!

fantstic matey, just bought a H+S infinity and was having issues with bubbles but now I know how to solve it, top job. Cheers pal

Fantastic explanation, helped me fix my problem right away! Glad I bought from you guys and will buy more in the future!

Absolutely fantastic demonstration. The details and explanations were excellent thanks you very much for taking the time to this together. I learnt quite a bit,

Great info! You helped me understand and fix my airbrush!

I have ordered a couple different things from you off of Amazon, and I didn't realize this was you, till a couple of minutes ago...lol ...By the way, the items were sent very fast,and exactly what I ordered.You are as thorough with your videos as you are with your airbrush supplies, and you answered my questions on there very quickly also...thank you.

i really appreciate the time you took to make this helpful video...thank you

Awesome video. I have 2 airbrushes which making bubbles and not spraying paint. I'll try to save them using your advices.

I got myself an airbrush to try and do some doll repaints and one problem that I had was figuring out why my airbrush was bubbling and this helped me big time because while I was cleaning out my airbrush a tiny little rubber band came out and I wasn’t if it was important but I’m glad found your video, thank you so much 😊 ❤

you saved me from buying another nozzle and/or needle. TY!!

hello my friend, i spend lots of time / watching youtube videos of bubble problem on airbrush, i am new in this , the thing is my airbrush got cluged cause i didnt use a filter when loading paint, paint was dirty, airbrush clugged, i dismantle the hole thing, cllean it with special solution, put it all back together again and i got bubbles on paint cup, i was about to order another airbrush, all the other videos have much information but not a single one expleins all the way you show what happen at airbrushing, i saw this video, i identify the part that needed adjunstment (nozzle cup) i thightned it enogh , and boila PROBLEM SOLVED, I AM SO THANKFUL TO YOU! the full story is a lot longer, but anyway , i stumbled uo on your video without searching, i was tired of many videos/attempts to resolve my problem in negative response, and after seeing this video, in 30 seconds problem was solved! thank you so much. have a great life!

Thank you so much for this video. I have an infinity and have been cleaning and cleaning the nozzle, because I thought bubbling indicated debris in the nozzle and so was sure there must be some tiny piece of debris in it that I just couldn't get out. Saw your excellent explanation of the 3 main reasons bubbling occurs, checked the nozzle seat, cleaned both surfaces carefully, made sure it was well tightened when screwed back in and...problem immediately fixed! I wish I'd seen your video a couple of months ago!

Thank you A LOT. Since I bought the infinity cr plus about 3 years ago, I have had the bubbling problem constantly, the only solution I had was to carefully squeeze the nozzle with pliers and even so I kept having the problem many times, it only happened to me with the nozzle of 0'15. But thanks to this video I have finally been able to verify that what could go wrong from the factory was the teflon ring of the 0'15 nozzle, after turning it over it has worked almost correctly (it continues to bubble but very very little, micro bubbles, but even with that, the flow works perfectly) I will try to buy new teflon parts and change them. Again thank you very much for this video.

Less than 1 minute into your video and you solved my problem 😁 Spar max 4 operating perfect again. Thank you.

Thanks, I'm just learning to airbrush for the first time and this really helped understand it better and to get my brush working well again. Especially the explanation about the paint path and making sure the nozzle is on tight. Got me up and running to finish my first painting project with the airbrush.

Excellent presentation. You thoroughly explained the problems that can occur on various airbrushes. You have a lot of knowledge!

Thank you for a very intuitive and clear video, it asissted me enourmously, as i had not realised the seals at the bottom of the nozzle could be replaced! Just saved me a heap of time and money, so thank you

Absolute legend , thanks heaps I was struggling hard to work out the problem , this was very good to understand why I was getting issues .

I fixed it while watching this video. Idk what it was exactly but i beleive it was cleaning it fully and tightening the tip well. Either way thankyou

Thank you so much !!! thanks to your video i finally find the crack that cause me the huge problem of the bubbles. :)

Best tutorial, covering every type of airbrush. You saved my day! Thank You sir! I have hit subscribe button...

This video has been so helpful. I have been fighting with my airbrushes for years. Currently trying to get my evolutions up and running both are giving me this blowback issues going to try replacing the tips like you showed in the video.

This is the most incredible video. The magnified pictures are perfect.

Thanks, Artem!! Air cap O-ring was causing the issue. Shewwwww! You're the best, buddy.

OMG you fixed my shit! Thanks bro really appreciate the clear concise diagrams.

This explained my problem. I thought it was the O ring, but I definatley pushed the needle up too hard (frustrated because of the cloging). Thank you so much!

Still learning after 25 years!! Thanks

Thx a lot, just fixed my airbrush. Greetings from Gdansk, Poland

Man you saved my airbrush thank u so much!

thank you! without this video would not heave realised my nozzle didnt have a seal :D prob flew off when i dropped the nozzle yesturday

Superb video - great insight and good use of examples and different types. Thank you 👍😊

I’m really glad you explained everything in a such a cool way with augmented photos because I had issue number 2 and it was driving my crazy. Don’t know how many times I used the ultrasound to clean it up and it wasn’t working. Thanks man!

Thank you for the help I got my airbrush working good now

Thanks for this video. I just got a new Harder and Steenbeck Infinity airbrush and used it once and it worked fine. Went to use it again and I didn't get any air flow out of the nozzel. I kept getting blowback and couldn't figure out why. Some how when I took it apart, I damaged the nozzel. When you explained step number 2, I immediately knew what my problem was. Thanks again.

Yup. Reason number 2. Thank you for such an informative video!

Thanks, couldn't figure out why I was getting air bubbles. I watched the video, understood the physics clearly, then just tightened my nozzle and problem solved!

this man is a true legend

great video! helped me alot

Brilliant video!!

Thank you so much!!! I fixed it thanks to you! It was the neddle. :P

An amazing video. Thank you so much for your help and advice.

Cheers. 4 minutes in and I´ve fixed my airbrush! Sorted.

Thank you for the info! Very informative

Definitely helpful thanks! I guess I was a little too timid tightening my new nozzle for Iwata Hp-C+ after breaking one off the other day and it was letting the air out ha.

Thank you so much sir for your effort and time to help us all out I really appreciate it

Thanks, your explanation solved my busted nozzle problem...

Wow buddy - this is so helpful

it was a nice guide. Thx man.

Great vid

Thank you so very much for this video, it helped solve my bubble problem!

That's solid advice, thanks man.

Just had this problem last night! 😬

Thank you for your detailed explanation. I have 3 airbrushes and 2 were blowing bubbles. I learned one had the nozzle cap not tight enough thus the nozzle was not protruding. The other one has the nozzle gasket missing. I made it seal by using beeswax. However, without the O-ring, the nozzle once again does not protrude past the nozzle cap. I need to find a replacement O-ring.

very helpful! thanks alot! I turned the seal and it worked!

thank you

this helped alot

i cant thank you enough, i really cant.so THANKS!!

Thank you so much one of the best guides for troubleshooting these problems👍👍👍 ? I'm pretty much done with my starter airbrush... I would appreciate if you can give me advice on purchasing a new pro model gravity-fed airbrush... My max budget is $150 for fishing lure detail

Great video. All aspects explained clearly and in a way most people will understand. I have a question......what do you do if you replace the nozzle and needle and follow all the procedures to the letter and STILL have bubbles in the cup ? ( I have an IWATA Neo TRN1)

Thank you so much for this video, I learned so much. I have 2 airbrushes, one for makeup and one for my art. Thank you again...........I love your rings...where can I get one like the ones you're wearing ?

Great information, thank you!

this is wonderful thank you so much

❤Very well explained❤

Good Show! Cheers!

thank you, I need a new nozzle

That was awesome and extremely helpful

Thank you this was very helful

Superb explanation!

Pls help I have the iwata neo and I think the air cap can go too tight too

Thanks bro !

Most problems getting paint out of the Airbrush, is too thick paint + too low air pressure, or clogged nozzle, really not the nozzle, but built up paint on the needle, between the needle and nozzle sides. It happens over time, wrong paint, too thick of paint, paint not properly shaken up, allowing solids to enter paint chamber. Pearls and Metallics are very bad about needing to be shaking up, shake up Pearls and Metallics until your arm wants to fall off, then shake 20 more minutes! Learn to clean your brush, and thin paints, if you clean your Airbrush and it sprays water great, then you add paint and it doesn’t spray good, it’s your paint thickness, or pressure or both, almost all paints I use need thinned, to flow proper, not all Airbrush’s are created equal, every Airbrush seems to be a individual, I learned by starting one pressure setting, and with thin paint, then thickened as needed, you will find what your Airbrush likes this way with different paints.

Very good video bro

Thank You for this information, as I own an Iwata, a Badger and a Harder and Steenbeck. Would polishing the needles do any damage, or affect the spray?

so the nozzle threads were stripped. i managed to use vaseline to fix it for now. but it's such a bummer. it was a 60$ portable one with one of those mini pumps. the pump isn't very powerfull :(

I only had bubbles in the cup half the time. Looks like my needles and tips were all mixed up. Had to piece together 3 sets of tip, spray regulators and needles..

You saved me from returning my brand new (cheap-as-f***) airbrush.

Cool video! But what about bubbles from trigger area in H&S Ultra? Any ideas?

I’m not sure if my airbrush is bubbling but every time I turn it on I hear this annoying air hissing out of the paint cup could that be related to bubbling. I’ve no idea what’s wrong with it.

This video is very informative! I have an Iwata HP-CS and it has begun to spray a little paint when the button is pushed down before it has been pulled back at all. Do you have any idea what could be causing this?

Not to long ago I bought the spiky buts bundle from you guys and it has been great, however I can't ever get my airbrush to back flow to mix paint or to clean itself. I'm covering the tip with my hand and nothing happens. I got the harder steenback ultra

I've got small bubbles coming from the side of my nozzle cap,what causes this?

The PS 770 Airbrush is one Airbrush that i ll wanna try out. Most because it's supposed to be an cheaper variation of a micron and because it is slightly bigger than other Airbrushes and i imagine it fits better in my Hand. Seeing ur video, i got bit worried about the nozzle size though.. and i m considering not to buy it. If it's problematic every time the tiny nozzle stuck with paint, to clean it, it takes out the fun factor in it. What's ur oppinion about it?

What would cause paint to flow when the trigger is depressed ??? I don't pull back on it at all, I just push down for airflow and I get both air and paint flow . My brush is just a simple Avanti gravity fed double action with the 0.35 needle . It's nothing fancy but I'm a beginner so I wanted to start out with something affordable

Hello! I just received my first airbrush. An Iwata HP CS and when I disassembled it I saw something on the needle. The needle is on one side a bit like an arrow tip but smoother. A bit faster on one side or like a small drop of water. Is it the way is supposed to be? (I guess not) thks!

Thankyou for your video, I purchased an airbrush, but when i tested it with water, only air comes out but when I completly remove the needle , then it sprays water. I have adjusted all the knobs and tightened the one holding the needle, still only air comes out. please can you help

polish your needle also 💦 better flow

I have had almost every issue that you've gone over. I use colored cocoa butter in our airbrushes (4). Models include a couple of Masters and neo and copycake. NONE of them work. I have checked all parts listed in your video which is great by the way. I"m thinking it is my hose. I can't see any obvious problems with the hose connection. Is there other parts I should check? Other things.. we use a heating pad to keep the brush warm so that the cocoa butter sprays. Perhaps the heat has ruined a seal? Help. I don't want to have to buy yet another one to add to our collection.

My nozzle had a crack in it causing bubbles in the cup.
