*The BSP connector working pressure to be used is the lowest value between the
comparison with the pressure of ports ends
(see charts: THREAD PORTS DIMENSIONS and DIMENSIONS FOR SAE FLANGE PORTS).
(1)Given dimensions are basic for a correct matching with listed weld-on nipples.
Male ends having D and D1 other than listed ones shall be matched with spherical or conical weld-on, nipples without O.Ring.
