An eversion and installation device and method for in-pipe use to line an underground pipe with a resin impregnated lining tube. A pressure vessel has a slotted gasket and a flapper, along with rollers allowing a collapsed lining tube to be extended into and through the vessel and cuffed and secured to the leading end of the vessel. The vessel is then lowered through a manhole passage onto the floor or trough of the pipe before fluid pressure is applied to evert the tube into the pipe.
