Note:
PRESSURE SEAL; or PRESSURE and RF SEAL ?
@If a Pressure seal only, then use a NON-CONDUCTIVE Gasket.
These are usually Silicon or Neoprene material, O-rings or Rectangles, designed to fit into flange grooves.
@If a Pressure and RF seal is required, then use a CONDUCTIVE Gasket.
These look similar to the non-conductive gaskets, but are filled with a conductive material, usually copper or silver. The exception is the Die-cut Gasket, which resembles the flange face.
