Response to a good example

A pressure acts on teh diameter at which the sealing occurs. Where teh pressure differential exists.

The 442 pounds comes from my limited understanding of your description of the tube diameter and 1,000psi. The actual force in the Hipac assembly at a full 3,000psi is only 147 pounds. nothing really.

The disco guage is sealing at a diameter of say 0.375 and a pressure of 2,000psi acting on that
means there will be a force on teh gauge threads of 222 pounds.

The size of a port has zero to do with reducing pressure when no flow exists through the port.

when there is flow through a port that is a different topic.
