ABSTRACT:
A venting packer tool for insertion into the open end of a pipe under repair and the like, characterized by telescoping body members hydraulically actuated to simultaneously operate an anchor to grip within the pipe and a packer to seal within the pipe, the body members having open communicating bores from the pipe interior to a vent tube for remote venting, and the tool inherently precluding accidental release when once set.
