Abstract

Simple handtool used with both straight and bent tubes. Plug consisting of two expandable O-rings pushed into or pulled out of tube with this flexible tool. Flexible shaft of tool threaded at inner (plug) end to engage or disengage plug when knurled handle turned. Results exceptionally low friction between shaft and tube. Allows insertion and removal of plug carefully controlled.
