Rubber, Wire-braid Hydraulic Hose Assembly, 0.38 Inch ID Hose, 3 ft Foot Length, 3/8 NPTF Fittings, Plastic Guard, Up To 10000.00 PSI

Burst pressure on this assembly is 20,000 psi, so there's a 2:1 safety margin built in above the maximum operating pressure of 10,000 psi. That said, the rated operating limit is still 10,000 psi and that's what you want to stay at or below during normal use. Pressure spikes that regularly exceed the operating rating will shorten service life over time even if they don't immediately breach the burst threshold.

Operating pressure on this assembly is 10,000 psi, and the burst pressure is 20,000 psi. So 10,000 psi is the stated max working pressure, not the burst number.
