ABSTRACT:
A service tool structure for effecting improved, simplified removal and installation of end fitting gaskets, adjustment of the adjustable valve depressor, and storage of spare gaskets and depressor elements. The tool structure is arranged to provide a partial installation of the gasket in the hose coupling with a first projection portion thereof and a completion of the installation of the gasket therein by a second projection portion thereof. The first projection portion may be further arranged to define structure for effecting adjustment of the valve depressor, the gasket being arranged to fit coaxially about the valve depressor adjusting structure. A threaded third projection portion of the tool structure is arranged to be threaded into the installed gasket so as to provide a sufficiently secure connection thereto to permit withdrawal of the gasket from the hose coupling as in replacement of the gasket. A fourth portion of the tool structure defines a suitable selectively closed recess for storing spare gaskets and valve depressors.
