ABSTRACT:
A pipe plugging tool for use in cutting and then soldering a fitting to a pipe includes a shaft, sleeve, compressible plug and nut arranged so that the nut can be rotated to axially compress the plug so that it radially expands into contact with the inner surface of the pipe. A stop member can be removably and adjustably positioned on the sleeve to set the location of the plug relative to the end of the pipe so that the nut is exposed when the fitting has been completed and so that the plug is spaced from the soldering heat sufficient distance to prevent degradation of the plug. A bag including a zipper and hook loop connecting fabric can be wrapped around the pipe prior to cutting. The bag has sleeves through which the hands of the operator can pass so that the cutting and plugging can be completed inside the bag and any escaping water collected at the bottom of the bag.
