A liner tube is provided for repairing either a single pipe line or a main pipe line (50) having a lateral pipe line (52) connected thereto. The liner tube assembly (10) includes a liner tube (14) impregnated with a liquid material capable of curing and hardening. The liner tube includes two hydrophilic sealing members(56, 58) positioned on opposite sides of the damaged portion of the pipe line. The hydrophilic seals (56, 58), when encountering liquid expand and form a liquid tight seal between the liner tube and the pipe line.
