The Working Pressure of each Hose Coupling End Termination Style is shown in the Technical section. In most cases, the Working Pressure of the Hose Coupling End Termination Style that can be chosen for a particular hose exceeds the Maximum Working Pressure of the Hose.
It is possible however, to select a Hose Coupling with End Termination with lower Working Pressure than the Hose. In this case, as noted in SAE J516 and SAE J517, the rated Working Pressure of the Hose Assembly must not exceed the lower of the respective Working Pressure rated values.
EXAMPLE 1.
T28D Hose Assembly with T2030-0812 coupling one end and T2090-0808 coupling other end.
From above table or from page 101, Maximum Working Pressure of T28D is 350 bar.
From page 203 and the technical section pages 496 to 500 the Maximum Working Pressure of T2030-0812 is 690 bar.
From page 199, and the technical section pages 496 to 500 the Maximum Working Pressure of T2090-0808 is 690 bar.
The Maximum Working Pressure of the Hose Assembly is therefore 350 bar, the lowest of the respective Working Pressure rated values (in this case, the hose).
EXAMPLE 2.
H5016D Hose Assembly with T7130-1620 coupling one end and T7030-1621 coupling other end.
From above table or from page 78, Maximum Working Pressure of H5016D is 350 bar.
From page 292 and the technical section pages 496 to 500 the Maximum Working Pressure of T7130-1620 is 280 bar.
From page 280 and the technical section pages 496 to 500 the Maximum Working Pressure of T7030-1621 is 420 bar.
The Maximum Working Pressure of the Hose Assembly is therefore 280 bar, the lowest of the respective Working Pressure rated values (in this case, the T7130-1620).
