Dear Catherine & all small torch users,
Here is what you need for a good code compliant Propane set up.
See image: http://www.ganoksin.com/ftp/DSCN0035.JPG
I believe it is code compliant being under one pound of Propane. All
disposable tanks are allowed indoors. Plumbers use them all the
time. I suppose I should say most instead of all, don't know all city
The screw in part on top of the tank is available at most hardware
stores where the barbecue grill parts are sold. You can unscrew a
plumbers Propane torch and use this part if necessary.
This screws right onto the disposable Propane tank.
This then screws into a barbecue regulator. I like the kind with the
red on off valve. I like to turn the unit on and off when not being
On top of that is a flashback arrestor available from Rio Grande.
Then your torch hose. These have the brass fittings with reversing
threads like all Propane and Acetylene hoses have.
The thread size for this all to screw together is standard 1/4", but
check when you order the parts.
No one sell this as a complete unit, you have to put it together
I've use this set up for years and it works fine and last quite a
few months before you need to replace the tank. I even had a large
casting torch with this setup for a few years.
Copy this parts in the picture and you are safe and well set up.
Good luck & best regards,
