How to Build a Portable Air Tank From an Old Propane Tank

Propane tanks are perfect for building a portable air tank. They are rate for pressures way beyond what your typical air compressor can produce. Since they are made with thick steel it would take nearly forever for them to rot out on you.
Here I build one from parts I had lying around and another one that only cost me $25 in fittings, a pressure gauge and some air hose.

Nice project, excellent videography. Very clear explanations and your level of competence with your tools and building these is clear. Thanks!

[@BuildNStuff]

Thanks so much! Glad you enjoyed it.

Sweet builds!!

[@BuildNStuff]

Thank you sir!

THIS FELLOW IS REALLY GOOD-Highly Skilled and Knowledgeable-----much better videography and commentary that most-I just subscribed. Worth your support.

[@BuildNStuff]

Wow, thanks!

[@enriquillobencosme995]

Nice project. I have a technical question. It’s anything you did before soldering to avoid an explosion? Thank.

[@BuildNStuff]

Thanks! Just take the valve out and blow it out with air at least. If you want more peace of mind fill it with water and then dump it out.

@@BuildNStuff Thank you so much from sunrise Fl.

[@travispolson4615]

Instead of blowing it out with air, you could fill the tank with water. Then you know 100% of propane is gone.

[@BuildNStuff]

Yes, certainly! I have done that in the past.

[@darthwelder652]

Fill with water and empty to ensure no residual gas.

Is your wire welder "from the harbor" or the Hobart?

[@BuildNStuff]

It's a Hobart

How much psi is safe for the smaller brown tank??
I try not to go over 130 on mine

[@BuildNStuff]

Propane tanks are rated for a lot more PSI than your air compressor is going to dish out. No need to worry about it just for air.

[@esotericjahanism5251]

a 20LB propane tank has a safety blow off valve built in rated at 375psi. So basically they can handle whatever pressure your compressor can put into it. That is as long as you aren't replacing the valve that came with it. Propane changes pressure with temperature much more than air does so they're made to be pretty beefy.
