The present invention includes a hydraulic cartridge and unitary frame connection for a high pressure high temperature press apparatus. The invention includes a hydraulic cartridge and a unitary frame threaded together. The hydraulic cartridge includes a cylindrical base and a truncated hollow conical section with external threads having a taper between about 2.650 and 5.650 inches per foot. The unitary frame defines an inner reaction chamber and has an outer surface. An opening in the unitary frame has internal threads extending axially substantially between the outer surface and the inner reaction chamber. The internal threads are adapted to mate with the hydraulic cartridge and the hydraulic cartridge is attached to the unitary frame along the length of the threads.
