ABSTRACT:
Method and apparatus are provided for sealing an open end of a sheathed cable. After removing a length of insulating jacket, the open end of the cable is placed in a pressure block and a viscous sealant material is injected into the block and into the open end of the cable. After injection, the cable is removed from the block and the sealant allowed to cure to a gel-like consistency. Fluid which may invade the interior of the cable above the seal is, therefore, prevented from passing by the seal and entering a transducer or other instrument secured to the end of the cable. In the preferred embodiment, a cable head, O-ring and transducer body are also provided to enclose the transducer in a substantially waterproof housing.
