Threading matches that setup. Thread B1 is 3/8-18 Male NPTF, and the other two ports (Thread 3 and Thread B2) are 3/8-18 Female NPTF, with threads called out to SAE J476.

For most industrial hydraulic setups, 6,000 PSI dynamic pressure is a solid ceiling to work with. Forged steel construction gives it the structural backbone to handle sustained load without the kind of fatigue you'd see in cast or machined alternatives. The forging process produces a denser grain structure, which matters when you're pushing fluid through a tee junction at high pressure repeatedly. Just make sure your line pressure stays within that rated limit and you should get solid service life out of it.
