The working and burst pressures are different for different diameters, the larger the tube within a class the lower the pressure rating. No matter however since no one is going to comer even close to the burst pressure with a normal air system.
DON'T DO THIS!!!!! But I have actually seen copper pipe used for hydraulic line where the pressures exceeded the ratings by more than 400% and that little tractor has been using those lines for nearly 20 years now.
I won't tell you who's tractor it is on!
