One method evaluated was a packing-gland-type fitting 

 v^ich seals by squeezing the insulation of each of the indi- 

 vidual conductor wires o Although a pressure test indicated 

 that this fitting successfully sealed around the conductor- 

 wire insulation, it was discarded as its large size would 

 have required lengthening the housing thus increasing the 

 handling problems. It also provided no method for discon- 

 necting the cable frcsn the central instrument aectiono 



A more compact design (Figure 6) was selected in whicii 

 small pressure- terminal seals, screw-mounted to the housing 

 bulk-head, may be utilized. Also^ a more compact clamping 

 arrangement for securing the cable armor wires to the housing 

 was evaluated in the test fixture, as shown in Figure 1-6. 

 A hydrostatic pressure test (2600 psig) of the assembly 

 revealed no leakage around the terminal seals^, or any slip- 

 page or failure of the armor wires. This housing was used 

 during sea trials.
