They are the pressure containing parts of the assembly that provide a metal-to-metal primary seal.
Subs are manufactured per different assembly modes:
NPT threaded assembly
NPST threaded assembly
Sub profiles are also machined/forged as an integral part of a piping element.
This is a forged part of the assembly that allows the connection of the two subs through a specific Acme or Iso thread.
