o/a porta torch tanks

[MilSpec1]

Hello,

I have one of those porta torch oxy/acet. rigs. I am wanting to use a larger size acet. tank (30 cf vs. 7 cf) but the porta torch acetylene regulator fitting is too small to attach to the larger bottle's valve. Is there a way to adapt the acet. regulator fitting to this larger size (proper gas fittings of course), or do I have to buy a whole new full size regulator/hose and torch kit?

Thanks,

Dean

The fitting that attaches the regulator to the tank threads in to the regulator. These are replaceable. Look up your regulator manufacturer, you want to get a replacement fitting that is compatible with CGA510. I believe your current fittings are CGA300.

Like 76GMC1500 said, you can replace the fittings in the regulators or just go to your near welding supply, they should have a huge assortment of adapters that would allow you to connect your regulator's up to any size tank's. Worst case go online and look for CGA connectors/adaptors. I started to buy on eof those but opted to go ahead for the big set instead. I also screwed up because I got a Q OXY tank which is fine, but I decided to go with a B Acetylene, so after cutting for a while or welding for a a few hours it's back to the welding supply for a exchange on the Acetylene. Go bigger if you can afford it, that is if you're going to use it often.

awesome, thats what I wanted to know, that I could use my current port a torch regulator and safely use adaptors.

Thanks!
