ABSTRACT:
A hand-held tool to use in extracting ring seats from housings such as small engine carburetor needle inlet valves is disclosed. The tool has a generally cylindrical handle means. From one end of the handle means a helical or threaded arm projects, ending in a tip. By inserting the extracting arm into the housing, pressing the arm end opposite the seal and turning the tool, the seal threads itself on and up the arm. Withdrawing the tool with the threaded seal on it from the housing thus removes the seal. A further embodiment combines with the foregoing a tamping member which projects from the other end of the handle means. The tamper, with its tip, aids in inserting a fresh seal in the housing.
