Abstract
Replaceable grease injection tubes permit removal and replacement of such tubes without requiring wireline and associated tools to be removed from a well, or wireline tools to be removed from wireline and thereafter spliced or re-threaded on such wireline. Replaceable grease injection tubes include opposing semi-cylindrical members that can be joined together to form a central bore for receiving wireline and facilitating a pressure seal using injected grease or other fluid having desired pressure sealing characteristics.
