you tell me,???

Also dose everyone know the working pressure and bursting pressure of the different sizes of tube you work with??????

What about DIY expansion & recovery Tanks ????? larger tank=more surface area(more square inches)= more pounds per square inch. bigger tanks=bigger bombs.

You Guys are going to give me a ulcer @ least use a pressure relief valve on any thing other than a single stage with a pure gas that pressure can be predicted. Also Buy tanks you know the pressure they can handle.

Some of the gases you guys are using are not commonly used as refrigerants and are extremely high pressure @ ambient temperatures.

I've said this before,many guys are over reaching your learning curve. I suggested you take a 8 to 40 hour class to get certified for recovery + be able to buy pure refrigerants and you would have been taught the basics, but our government screwed that up by providing a on-line open book test where you only have answer 50 question and get 80% correct with a open book. defeated my intention for you guys to learn about refrigerants,specific gravity and pressure conversions.

But this is a International Forum, Take a good look how that copper tube distorted and the flats plates bulged. I actually applaud the person who posted that pic as most hide their worst mistakes & we know many have happened. I hope every time you consider making something that deals with pressure vessels, picture that DIY bulging distorted Copper Tube then

Please reconsider,I don't want anyone here hurt.

This is not a game!!!! and there are no "do overs" or "second chances", even if its a serious injury,who wants there eyes blown or burnt out?

you are no longer wiring up 12volt DC fans, give pressure and these gases the respect they deserve.
