20 located along a second end of the shell 12 a second generally semi cylindrical shell 22 also includes an inner surface and outer surface with a proximal and distal endwall forming a mirror image of the inner surface and the endwalls 18 20 of the first shell 12 the first shell 12 is securable to the second shell 22 by use of screw fasteners 24 and bolt fasteners 26 it should be noted that various fastening techniques may be used that are capable of maintaining the shells together when the cavity formed between the shells 12 22 is subjected to a pressure in excess of 3000 psi pressurize fluid may be injection through port 17 with a gauge 19 mounted directly or indirectly to the stator providing an accurate indication of cavity pressure a gasket seal is placed within gasket slot 30 to prevent fluid from escaping the shells the endwalls 18 20 of the first shell 12 and the mirror image endwalls of the second shell 22 cooperate to form an aperture 32 adapted to encircle a cable having a circular or non circular cross section traveling axially through the stator 10 to allow the stator 10 to easily coupled to a cable the second shell 22 can be hingedly attached by attachment arms 34 and 36 that engage a receptacle 38 formed in the first shell 12 the hinge design allows.
