The HTHP, HP, and C versions have a ceramic tank seal, and graphite
gaskets - no O-rings are used. The final rating depends on flange selection.
A difference between the HP/C and HTHP coaxial versions is material for
some parts; PFA/PTFE for HP/C, and ceramics for HTHP. Ceramic spacers
allow for usage in applications with higher temperature.
The following table gives the temperature ranges for tank seal with different
O-ring material (applicable for the Standard Tank Connection):
