SAE J514 Working Pressure Ratings
Capable of 4 to 1 Minimum Burst
Note: In the case of a fitting that is a jump size, it is recommended that the lower pressure of the two ends must be recognized as
the working pressure rating for that fitting. This is also the case if the fitting has one or more different style ends. For example,
straight treads to pipe threads. In this case it is also recommended that the lower pressure rating of the two different style ends
must be recognized as the working pressure rating for that fitting.
