ST848 tool is used to facilitate the installation of O-rings on hydraulic fittings.
The ST848 tools consist of a thimble to slip over the threads of the hydraulic fitting, an expanding body to act as a guide for the slip ring, a slip ring to push the O-ring over the thimble and into place on the fitting, and an extracting rod to extract the thimble after the O-ring has been installed and the tool removed from the hydraulic fitting.
The dash number after the basic part number (ST848) indicates the size of the flared tube
fitting or hose fitting on which the O-ring is to be installed (Table 1).
