Apparatus for sealing a perforated liner to a well casing. A cylindrical liner having a sleeve thereabout is associated with a deforming tool which is telescoped thereon and extends to the sleeve. A portion of the sleeve is spaced from the cylindrical liner to receive the deforming tool. A pressure fluidizing solid is located within the sleeve. An impacting system for a hydraulic deforming mechanism are employed to force the deforming tool against the pressure fluidizing solid which in turn deforms the sleeve outwardly against a well casing.
