An apparatus and method for installing a liner in a pipe, including a flexible tube assembly (2) with a proximal and a distal end, where the proximal end is attached to a proximal collar fitting (3) and the distal end is attached to a distal collar fitting (4). An inflatable bladder (110) is disposed over the tube (2) and the ends of the bladder (110) are secured to the collar fittings (3,4) forming sealed connections with the collar fittings. The proximal collar fitting (3) has connection means to connect to a guide hose (5), and includes at least one conduit for a fluid to inflate the inflatable and deflate bladder.
