Oxygen bottle valve removal whats inside ?

[@freddieb4268]

Just an update, I was able to remove the stem valve fairly easy from my oxygen tanks. I just placed them into a vice, sprayed some WD-40 on the stem valve and used a pipe wrench to loosen it. Thanks again for making this video so I knew what direction to loosen the stem valve.

[@floridaed91]

Never use any oil on a oxigen tank ...high risk of explosion Research it !!!

[@HarlanHarvey76]

Thanks, almost 10yrs later and this video was exactly what i was looking for!

[@bertkilborne6464]

I got a tank at the scrapyard awhile ago and I almost broke my vise loose from the bench trying to get that valve out. Thanks for the information. it saved some time

[@421eaglerocks9]

Fyi...get garden hose, cut a slice along length of 2 three foot pieces. Tie together then fix them to a pole stationed in concrete. Get cargo strap and double wrap bottle to pole firmly. As tight as you can, against the cushioning on the cut hoses of course. Now you will be able to wrench of the regulator in a normal lefty loose kind of way. Hope this helps you in the future. Good day Sir!

[@xxoakparkxx]

Thank you for this video

[@TheChipmunk2008]

I knew for the regulator thread, that flammable gases are left hand, and oxidisers right hand. I never knew that applied to the valves into the cylinder as well! Thanks for posting, you're right, you may well save someone time and frustration in future :)

[@NOBOX7]

***** hey thanks for the input friend i never herd the axiom "flammable gases are left hand, and oxidizers right hand" i will remember that , but hey check this out i have a small oxygen bottle the propane tank kind and its a left hand thread ,

[@HavanaWoody]

NOBOX7 one of the first things we learned in ag shop. left hand threads will always have a slot on the hex

[@NOBOX7]

Havana Woody hmm didnt no that , i will look for the slot

[@shannondailey2204]

Thank you!!! You saved me 3 hours also

[@gordonmercer6742]

just got one of these from salvage. could not remove the valve . will try notching method . I want to make an air tank to mount to my M Farmall tractor attach a line to a steam whistle so grandkids can toot when they come to visit . thanks for the great video.

good luck friend hope it works out for you

I’m getting ready to change a valve like this. Thank you!

[@murraymadness4674]

Thanks for the video, I too spend so much time trying to find info that seems simple yet no answer. Google just wants to sell you stuff, or show you what is 'typical' or 'common'. I got like two dozen of these, fortunately they removed the regulators. Not sure what to do with them, but making a lightweight propane tank seems the plan for at least a few of them.

[@rudolf895]

[@p.g.9835]

Make sure you remove the oxygen by turning the knob on top to the left. There should be no problem unscrewing once oxygen is removed

[@David-hr5ml]

Thanks brother. I couldn't find any info on the search engine. What size thread and diameter fitting?

The entire top of the tank has to be removed the valve before selling So it doesn't explode when being crushed in a car packer

Thanks mate - Got to remove one to day here in Australia .

[@bettabegoodjr2104]

So I use co2 in my planted aquarium and my father brought me some 5lb oxygen tanks.. can I convert the valve on one of these o2 tanks to co2 for my aquarium? Or do you think a welding company will just swap out the o2 tank for co2 tank?

[@diyguynoble7877]

I just subscribed to your blog because you my friend are valuable, I got nine of these

[@luigiprovencher]

How did you release the remaining oxygen?

[@MegaBoilermaker]

Never stand in front of a cylinder valve when removing it. All combustible gasses should have a left hand thread.

Do you think it would be possible to make a M9 oxygen tank fit a 40mm thread hose connected to a 40mm gas mask? I want to try to make a oxygen respirator with my Gp5 and use my C3 as a normal gas mask, since gas mask don’t provide oxygen I would like to know from someone who knows about tanks and threading if this is possible.

How to rebuild that on off inside of that stem

[@sharkyballoons]

Thank you! I just used this helpful knowledge today.

[@NOBOX7]

to any body watching this , it may be possible to make 2 notches on the neck with an angle grinder that would allow a crescent wrench to hold the bottle , wish i woulda thought of that when i did mine ....

[@left_Dane_right_Dane]

Just did what you suggested notching. I put one wrench inside a trailer hitch on my truck and put a breaker bar on the other wrench. Had someone hold the bottle and it came off easy peasy.

[@NOBOX7]

Dane Mehl freakn awesome bro , so glad it worked , it took me an hour of fooling with mine , i thought about the notch after the fact ,,, dammm

[@ginkumpow3726]

hold the cylinder with a chain wrench. the neck is standard NPT threads

[@miketripletfab4098]

On aluminum cylinders it is a UNF thread

[@tonyb8443]

What is the valve thread size? Doesn't look like a pipe thread

[@CommanderKlag]

What about a sandblaster ? Would it do good for that ?

[@davidbarnard9186]

Would it be easier once empty, to put some of the New SuperZillia in the bottle, and leave it up side down for a while. I have several oxy bottles, and have been looking how. To remove. Brass fitting. I hope to use mine for Air brush bottlers.

[@NOBOX7]

make sure it has no oxygen , in it or it could kill you

[@NOBOX7]

Yes if its empty . bottles with broken valves can kill you

[@stephenhess9806]

thanks. saved me a lot of time. just wanted to know if left or right hand thread. I picked up a couple of these at a garage sale and want to turn them into gongs...

[@yahwehwarrior2207]

you may need to grind a flat notch on the neck on 2 sides so a crescent wrench can be used to hold the bottle , i regret not thinking of this when i made this video

[@stephenhess9806]

good idea. I'll try that. I'm going to need a bigger wrench to pry that thing loose. I'll try some heat with a torch to see if that makes it any easier.

[@NOBOX7]

ok be carfull and if your gonna use a torch try to not heat the valve up, just the neck this will allow expansion to do a better job , if you hit the valve with flame also it to will expand . that sucker is on there tight bro and it seems they used a lock tight compound as well , if you have to take some rope and make a hoop about twice the size of the tank then stick a pipe inside the hoop and the tank and spin the pipe so it causes the hoop to twist and grip the pipe , if you make the hoop wrap around the pipe a few times before the twist its even better , its a special rigging technique

[@11kmdeep]

Thanks for this gem. This rigging comment and the video saved me a lot of grief. Found a strap and some pipe wrapped it up and had the valve off in a couple minutes.

[@debbieball5154]

I hope that you can help me. I have been calling oxygen supply companies and have been on line for nearly three hours myself trying to find out what the purpose of the paper or plastic clip that covers the two holes and has a washer inside of it on the E Tank. Do you know? Thank you for your time.

[@NOBOX7]

I think its just to keep dirt out of the holes when not in use

[@miketripletfab4098]

The washer goes between your valve and your regulator to provide a leak proof seal

[@josephcassidy4158]

Thank you so much!

[@robertjordon5782]

Good job

[@jamesdorrill9933]

I wrapped a chain around mine with a chain binder to brake mine a loose

[@briangingras5886]

I was told by a gas company not to cut the top of the bottle off. If I couldn't remove the valve with a wrench which. I should be able to do because if there was gas in the tank of the pressure that the valve of stuck cutting into the tank will be a dangerous situation

[@briangingras5886]

I guess if there was gas in the tank even when Iunscrewing. You would hear the gas through the threads as you're unscrewing before you unscrewed completely?

Can you use medical Oxygen cylinder for indestrial use by removing and changing the valve Can you give me some information

[@left_Dane_right_Dane]

Thanks man. I have 2 m9s I'm trying to get the valves off of. Still haven't managed to get one off. Huge pain in the ass. Cant drill into it like you did. Not sure how I'm going to conquer this. Been hoping some WD will seep in the and I keep smacking it with a hammer hoping to loosen it.

[@NOBOX7]

yeah they make a special vice for these , be very carfull , if there is still oxygen in bottle when you try to open it the aluminum can explode like thermite , this happen to a guy who had a bad valve and a full tank, he tried to crack the valve loose just enough ot let the o2 seep out and the thing exploded and blew his arm off , there is a web page about it

[@NOBOX7]

have you tried rapping rope around it with like ten loops then nail the rope down to a work bench . or rap rope around it very tightly like ten loop then tie the left over to a tree so the bottle is tied to a tree if you tie the rope correctly it will tighten as you turn the bottle if you have it rapped the wrong way it will loosen , its hard to explain. it would of bin smart of the bottle makers to put a wrench notch on the neck of the bottle so you could use 2 wrenches to loosen the neck . would it be possible for you to notch the neck with a angle grinder on 2 sides so a crescent wrench could hold it ?

[@left_Dane_right_Dane]

They said "will ship empty" but I opened the valves and they both had quite a bit of air left in them. It seems like it's pretty thick so I might notch it, that's a good idea

[@freddieb4268]

I have two of these I was hoping to use as extra tanks for my compressor. Not sure if anybody has used them for that.

[@NOBOX7]

they would work very good for that and would never rust out like the chinese ones

[@freddieb4268]

My only concern is finding fittings that would work with those tanks. Thanks for making this video by the way, it will be very helpful when I get around to working on my tanks.

[@NOBOX7]

just drill a hole and tap some threads , very easy to do , in fact that's what i did , i think it was a 3/8 tap and compressor fittings can be purchased at that size

[@exploderx]

Thanks! This told me all I needed to know.

[@brianlink391]

Could just had used an impactor if you have one. Weld up a DIY fitting to a socket and there u go. That's if you have a welder too. :-)

[@juancarlosamarillas8240]

Hey guys.. Does anyone know if it is possible to convert a oxygen tank like this into a propane tank? Tia

[@mikegauthier6364]

I have multiple oxygen tanks of different sizes. What I really wanted to know is if I could convert it to propane and if there was a fitting that would work for that with the threats that are already there. Since these heavy cylinders are becoming obsolete I thought it would be a great idea to repurpose them to propane. I understand oxygen tanks can hold more PSI then I normal propane tank can and it is a bit of an Overkill According to some.

[@benm9382]

You can, but you need to take into consideration that you have to change the valve to a pol type so, it has the right pressure release device for LPG. Then you have to calculate the WC and work out 80 percent of that so you dont over fill it with too much propane, and have enough room for expansion.

[@MrDavesbox1]

so the inside lining is steel?

[@Felisargyle]

Tape this on the edge of a table with duct tape use about 8 - 6 pieces and do what he did in the video and it will unscrew
