ABSTRACT:
This disclosure relates to a tube marking tool pivotally mounted in a housing such that the end of the tube can be placed in a bore provided for this purpose in the housing. A marking tool is pivotally mounted in the housing and when moved downwardly, relative rotational movement between the tube and the housing provides a mark on the tube at a predetermined distance from the end of said tube. This mark is then used to provide a convenient gage mark for indicating that the tube is properly made up with a fitting of conventional configuration.
