Why not just use an air brush ? They come in a variety of sizes able to handle a variety of liquids. Much easier to refill and you have only to change the liquid in the airbrush instead of having many different cans with varying liquids in them.

Why not just refill it through the nozzle instead of making that stupid contraption? I've done it before and it works just fine.

[@kmoecub]

There are commercial versions of this, which are made from thicker metal and meant to be reused for decades. They are also much easier to re-fill as they have a dedicated fill opening that's much larger than the schrader valve opening. What you've done does work fine, but I'd not reuse a spray can that's ever been dropped.

[@sbreheny]

These cans normally use a propellant, though, which maintains the pressure by the propellant continuously boiling and making more vapor. With compressed air, the pressure will drop really quickly when you press the nozzle valve to spray the contents. You'll have to keep adding compressed air and it will be annoying. If you try to make up for this by using a higher air pressure, you risk an explosion from overpressurizing the can. Also, these cans are not designed to be refilled so the fatigue caused by cycles of pressurizing and de-pressurizing is not taken into account in the design.

[@VintageEngineRepairs]

Thanks for sharing, yep, best to add low pressure and just give it a couple pumps with a hand pump every so often :)

[@HeyChickens]

Honestly, the whole thing about fatigue from cycles of pressurizing and depressurizing is highly dependent on how fast those cycles take place. These cans have propellent in them, so as the ambient temperature changes, these cans have to be able to withstand some pretty significant changes in pressure. Now obviously these changes in pressure will be very gradual, but nevertheless they do have to endure some significant changes in pressure. So as long as you keep the changes within reasonable limits, the cans should be good for a good while. But it would be a good idea to get a new can every so often and not risk it.

[@murphymmc]

@@HeyChickens Some cans list the psi on the label. Many are as high as 90psi, a good solder joint will withstand much more so there is a pretty good safety factor with lower pressure. I've refilled the air cans used for blowing the dust out of electronics by using the whole valve stem. It only works on those cans that have the tube protruding once the push cap is removed. The valve stem pushes down on the exposed tip, the rubber seals against the can, works well for quite a few refills.

[@802Garage]

FWIW my research says these cans are generally charged to between 50 and 100 PSI off the shelf and I found a quote on a forum that said "Looking up on the net, it appears that US aerosol cans come in classifications, DOT-2Q, and DOT-2P. DOT-2Q are required to withstand a minimum of 180psi without buckle, and 270psi without burst (at 130F = 54C temperature). Dot-2P have a lower burst pressure of 240psi (the difference is in the metal thickness used to make the can). Apparently American WD40 cans are marked DOT-2Q, but I have not found any marking on WD40 made in Au cans. The Europeans use different standards, not DOT." I also found another page titled "Europe versus US on aerosol can regulation" which lists pressure ratings for most cans at around 10 BAR minimum and burst pressures 20 or 50% higher than that. So really almost any aerosol can should be able to be charged up to 100 psi with no issue, but I do agree it's best to be cautious. Personally I have pushed cans to 125 psi or close with no issue, but I'm not recommending that, it's not necessary.

[@lukasandrysik3666]

I have refilled those cans several times (another method using the existing valve without drilling another hole) . But I DON'T recommend using AIR to pressurize them. The air (oxygen) makes nice flammable (explosive!) mixture with the liquid inside. With water-based chemicals it promotes corrosion (rusting) inside. I use CO2 instead. It also looks like the CO2 dissolves in the liquids so there is more propellant available and the spray pattern (atomization) is much nicer compared to the air at the same pressure. You could also use propane, butane, isobutane - for example from those "compressed air cans" - they are most ofter just propane+butane mix. Just watch the pressure so you don't overfill those thin-walled cans. I fill those to around 5bars at room temp

I actually did this about a year ago myself! I used a wd-40 can, and I just put whatever random general purpose oil I have on hand for oiling stuff. But I used a slightly different brass fitting, one that is made for refrigeration. And I soldered it on with a small pen torch and used 60/40 tin/lead solder, so I didn't have any issues overheating the valve. I will of course have to keep in mind that since I have lead solder on the valve, I should not drink the oil, lol.

Wow. So you're talking about a bushing w the securing nut inside the can? That seems like a whole lot more work. Also, imo, sorta defeating the purpose of the cheap, universal schrader valve.

No caustic liquids on the rubber seat, of course, but they're designed for 30+ psi. (Meaning the can is the weak link. Not pressurizing the can)

Then I inverted it in the replacement fluid, and pressed the valve, until the can stopped sucking it up. Once done, a foot pump, for car tires, was used to force air into the can, by carefully timing the valve presses with the foot presses. It works, and saves currency lumps too :) .

And that stuff burns fine in the little screw-on burner. At 20 deg C it took the same time and weight of gas to boil a cup of water. In cold weather you need to warm it up more in a pocket (or armpit lol)

These cans are pressurized with a propellent rather than air. Propane is commonly used. It would be possible to use a can of propane from a torch etc. to add the propellent rather than using air. Also, some automotive paint shops can make up a can of paint so they could supply a new empty can and place the valve in it before they attach the lid to it. Many possible ideas.

Any aerosol can can be refilled without even soldering the valve. It is enough to make an adapter out of plastic, which can be used to pair a syringe and an aerosol can. With the help of a syringe, any liquid can be poured into the container. And then add the propellant using a suitable adapter and temperature difference. LPG can be used as the propellant. In this case, a constant pressure is maintained in the tank until the propellant is used up. The process is similar to refilling small gas cans.

[@VintageEngineRepairs]

Thanks for sharing! You should do a video on it?

[@hikewomeat]

I quite often use gas in small cartridges designed for use with a compact burner. This process, of course, I can film. As for refilling aerosol cans, I haven't done that lately, but maybe if you're interested, I'll repeat this procedure for shooting. I'll tell you how it all started. It was a long time ago. Then in our country it was not easy to buy a pepper spray for self-defense. I was still a schoolboy and this topic interested me a lot, as the times were turbulent. Among other things, I knew chemistry very well, and now I work as a chemist by profession. I decided to make my own pepper spray. But not just peppery, but much more powerful, containing a more serious tear substance. I have explored several options. One of them was a-bromobenzyl cyanide, the other was 1,3-dichloroacetone oxime. The last substance is called nettle gas. These are very serious irritants. I synthesized both. I used sulfur dioxide as a propellant. It is an easily liquefied gas, it becomes liquid upon slight cooling. Used cans of deodorant. Fortunately, I did not have to use these devices for their intended purpose. It should be noted that the container containing a-bromobenzyl cyanide began to leak right at my house. Since this substance is unstable and releases hydrogen bromide, which is highly corrosive. It was a real disaster. I had to use a gas mask. But everything went well. I made the adapter from the polyethylene part of the coaxial cable, drilling holes on each side so that the rod of the aerosol bottle and the nozzle of the syringe would fit in there perfectly. All this was over 30 years ago. Time passes quickly, but something is not forgotten.

[@VintageEngineRepairs]

Haha, that sounds very interesting and way beyond what I’d ever feel comfortable making 🤣 stay safe and thanks for hanging around here! :)

[@MrTheHillfolk]

If it has just lost the propellant and you need to pressurize it ,just use a rubber tip blow gun against the spray head and open them both at the same time. Wear some glasses because if you're not good there will be a little spray flying around

It is a much better idea to use a pump sprayer, you can refill them easily and they are much easier to strip and clean. You can but them in different sizes I use 500ml and 1l and you can select how much pressure you want. Those cans are designed for single use the nozzles tend to get clogged up. The difficult part is acquiring the stuff in bulk containers. Also this is quite dangerous if you do this to cans of flammable material you have compromised the pressure vessel they are likely to leak or blow at the worst moment. (Sods law) They won't leak 'air' they will leak flammable gas or liquid even from the top. For about £3 you can buy a 500ml hand sprayer designed for corrosive liquids that will be safer, last longer and hold more product.

[@VintageEngineRepairs]

You’re welcome :)

[@Agnemons]

Those cans are designed with a safety margin for a single fill. Multiple reuse's will tend to stress the metal causing it to fail eventually. Even relatively low pressure's can have catastrophic consequenses. Any number of substances that most people believe to be quite benign and safe become explosive when areosoled. Such as limestone dust, flour dust, aluminium powder, iron powder and so on. A recent example is the explosion in a grain facility in Turkey. Which was, in all probability caused by grain dust. If you were to even partly fill that can with Methelated spirits and it exploded you would, in effect, have created a fuel/air bomb. A fuel air bomb is the largest non nuclear weapon in current arsenals. Filling a can with propane or some such is like playing russian roulette with all chambers loaded. If you want to do something like this go out and buy a pump up plastic bottle for a couple of dollars and use that instead. The upside of that is they are usually extremely easy to fill and normally have a safety valve to stop over pressure.

[@VintageEngineRepairs]

Thanks for sharing! They are rated to over 300 psi new, adding in 10-20 psi will not stress them enough for any failure that will cause any harm. However if you don’t feel safe, I did mention a refillable version.

[@Agnemons]

The problem is that alot of people will not be content with 10 or 20 psi. Additionally, even factoring in the resistance in the air line, it would be exceedingly easy to put in 100 psi, particularly if the can is 3/4 full of liquid. There is not a lot of head room to act as a buffer.@@VintageEngineRepairs

@@Agnemons As mentioned, I can’t give a safe PSI, there isn’t one. However starting off with 2-3 psi (which will never cause any damage if it fails) and then going from there is a sensible solution.

One has to take a certain amount of responsibility, especially when warned of the dangers and given a very low recommended pressure. Thanks again :)

Awesome vid. Isopropyl alcohol is a great liquid to use for brakes, mass airflow sensor, throttle body cleaner etc. It must be above 92% though

Great Video - you showed al the steps and things to look out for and it was fast - it is great for being able to put other fluids in that normally are not put in sprays - like light oils or brake fluid etc

I punched a hole in one with a tapered punch creating a threadable collar in the can top. I then threaded the "collar" and screwed in a valve. Worked great.

I have the refillable can I bought from Amazon. Works great I’ve had it for over a year now. Only $25 at the time but I think they’ve gone up in price since But I think I’m gonna make another one since I literally just got 4 schrader valves two days ago lol

about 22 ish years ago i bough a commercial version of this from harbor freight the whole spray nozzle assembly unscrewed so you could put your material in then had the air chuck in the bottom... material was much much thicker then that of whats used to make a regular spray paint can kind of sad they discontinued them about 18 years ago would really like to have another one

[@tonymontana897]

So what's the optimum amount of pressure you've found to have worked best ?

[@VintageEngineRepairs]

Hey Tony! I have explained this in the video. I can’t give a perfect PSI, start with a low pressure 5-10 psi and go from there until you get the atomisation you’re after. I have gone up to 100 psi, but I don’t recommend it and it’s not necessary!

[@chrisallen2005]

Did you not listen to anything he said?

[@tonymontana897]

@@chrisallen2005 Hey Big mouth, I did, but he didn't specify the "optimum" amount. Read comments very carefully before you shoot that big mouth off. Ok ?

[@VintageEngineRepairs]

Hey Tony, it’s all good mate, no I can’t give an optimum amount, best to start low and use as little pressure necessary to get the atomisation required. Better to refill with air a few times (just a few pumps of a hand pump) and keep it low :)

[@manofallmasterofnone1020]

Dude! I tried this a while before this video and I thought I was crazy!

[@VintageEngineRepairs]

[@christianfriedrichs]

Could you get the compressed air through the nozzle without the need of modification?

[@VintageEngineRepairs]

Yep :) but you can’t add fluids.

[@JohnDoe-md2sb]

Did this a couple of years ago but just as an air sprayer. Good in theory but you'll never get anywhere near the amount of compressed air in there. I use it with a portable compressor that fils it as I use it but then you get moisture that gets into the equation. I've gotten the can to 90-1000psi, but it gets pretty hot. Have yet to push the envelope. 💥 In this setting I'd just use your average spray bottle...messing with the shradder valve and compressor isn't really worth the trouble, not to mention the risks. Interesting video however. 👍👍

[@ukhan507]

Can we use two parts epoxy to fix the schrader valve to the can? Or using soldering method have any advantage over epoxy?

[@VintageEngineRepairs]

Either honestly, the key is keeping the pressure to an absolute minimum!!

If you fill the can completely with water (once) it will purge any explosive gases. Super safe final step when rinsing out the original ingredients.

[@b5a5m5]

Do consider that you are pressurizing combustible liquids with atmospheric gases which contains oxygen. The can could now explode in the unlikely event it is somehow ignited. If you can, you should use argon or co2 (probably from a welding tank if you have one) or some other inert gas to be extra safe when pressurizing these cans.

[@VintageEngineRepairs]

[@Brian-jz1pi]

Couldn't volatile liquids explode with air added like oil or fuels?what do you think a good limiting psi would be?10 p.s.i.?

[@VintageEngineRepairs]

I have tried different PSI, and although I can’t give a recommend number, I have tried everything from 5-100 and the higher you go the more atomisation you get. Best to start with a very low number 5-10, check the valve is sealing and see how how you like the pressure / result and go from there. Use as little as pressure as you can get away with! (100 is unnecessarily high, I don’t recommend it!). I think a max or 40 is all you need, but again, I can’t give a safe recommended PSI, these are modified cans!

[@nicholashacking381]

I have to say, I wondered about that too. We're always warned about the hazard of using flammable oil or grease in compressed air systems...

[@emanuelmifsud6754]

There's no way that manufacturers fill a volatile fuel chemical into a can and pressurise it with air. When released, the slightest ignition source could make it explode. This fellow needs to be very careful what he recommends. If he is a expert on explosives of fuels he'd be wary what to say.

[@balint133]

@@emanuelmifsud6754 yep, I don't think pressurizing a modified can full of volatile compounds with air is a good idea. If I ever wanted to DIY this, I'd get a nitrogen tank and pressurize it with nitrogen instead.

[@emanuelmifsud6754]

@@balint133 You are correct. Nitrogen wuld be fine. A volatile fuel mixed with oxygen is a bomb waiting to happen. This video needs to be VERY careful what he recommends to fill the cans. Some cans are filled with butane, but ONLY butane, and they are safe. If they filled a can with butane and oxygen they are creating a potential bomb.
