ABSTRACT:
A tool is provided for the extraction of preformed fittings placed in a peripheral groove hollowed into the wall of a bore. A pincer device is formed by two tapered noses, one fixedly attached to a hollow body and the second attached to a piston capable of sliding within the hollow body. An adjustable stop controls the width of the pincer device, and a reference marking indicates the setting of the stop. A grip sleeve and positioning holder assist a user in operating the tool.
