What is the difference between working pressure and burst pressure?
Burst pressure is the point where the part may actually explode under the pressure. In automotive applications, it is common to use a 4:1 correction factor for the maximum boost that you should run through a part. IE if the burst pressure is 200 PSI, the working pressure (or most pressure you should run) is 50 PSI. Even so, at levels over 50 PSI, blowing hoses off their joiners would probably be the biggest concern.
