Better alternative to a Smith Little Torch or Gentec Regulator for 1lb propane tanks?

- It should go without mentioning, but this method should be used at your own risk!
Some notes I forgot to mention
• Each piece for this setup is heavy-duty and only contains two rubber gaskets. One in the DOT 39 adapter and the other on the needle for the valve. Both can be replaced easily. Unless extreme damage occurs for some reason, this setup will easily last a lifetime. Also, each individual piece is replaceable interdependently, of course.
• As for the pressures with this system. When the tank valve is open and the torch valve closed, the vapor pressure will equalize in the line and headspace of the tank. Since the tank valve would only be left slightly open, once opening the torch valve, the line pressure will quickly drop in the line. So fast, in fact, that by the time the torch is lit, it will have settled, which is why I have not experienced any difference in torch behavior between this method and using a regulator.
• In case of any confusion, I would only use this method on these small tanks and not on anything larger.

The best option for this fitting is at a local welding supply. Here is a link to Airgas, this item can also be purchased at mcmaster.com

Thank you so much for coming out with this video. I've looked for a long time and this is the only one that I've ever come across. I am eternally grateful. God bless you.
Excellent video, only one of its kind I could find. Very informative. Look forward to putting it into practice 👍🏾
I’m not sure if this makes sense. The little smith requires oxygen and propane, 2 lines.
Hi thanks again for the upload and information. I've constructed a needle valve setup similar to yours and connected my disposable tank to it and a flashback arrestor. I've fiddled about with both valves but I think the pressure is to much as can't get flame to hold steady without extinguishing. Do I need an additional pressure regulator? As I'm pretty sure that gas is coming out at alot more than 10 psi which is recommended for the little torch... Any advice would be welcome..
Hi thank you for video.
Is this method will work on disposable oxigen Bottle?
No, the disposable o2 tanks are left hand thread and would require a different adapter. Personally though, I would highly recommend not even bothering with the disposable tanks (1.1cu ft) and just getting either an MC (10cu ft) or R (20cu ft) size O2 tank. You can pick up either for right around $70 and have 2-5x as much o2 as you would buying disposables, plus the larger tanks can be refilled for $10 so in the long run you save a ton of money while making less waste especially if using an oxy-propane torch since they require 5 parts O2 for every 1 part propane burned (4:1 for oxy-Mapp, 2.5:1 for oxy-acetylene)
Thanks
