removing regulator

[pat123]

hey I have some air tanks but i can't get the regulator off. the tanks hold 2000 psi and the regulator is just to hard to turn off. do you have any ideas on how to get it off.

[hi]

make sure the tank valve is off before you try to take off the regulator. then bleed the lines/ regulator and use an adjustable open end wrench to unscrew it.

thats what i was taught to do in my welding class. it what the book ways. it says to use a 15'' wrench, any adjustable wrench will work.

ps- an "adjustable open end wrench" is the offical term for a crescent wrench. crescent is just the company that makes them, not the actual name of the tool.

its like calling a hammer made in china a "china hammer"

What kind of "air" tanks are they? Are they scuba tanks, hpa or ?

2000psi seems low for an air tank.

Maybe a picture?

But for now;

Some tanks have left hand thread for the regulator attachment.

You should be able to see a few threads if you look carefully, make sure you are turning it the correct way.

Thanks I got it my friend stood on one 18" pipewrench and i stood on the other and it eventually gave. it is one of those tanks for firefighters to breathe with.
