Abstract
A liner tube is provided for repairing either a single pipe line or a main pipe line having a lateral pipe line connected thereto. The liner tube assembly includes a liner tube impregnated with a liquid material capable of curing and hardening. The liner tube includes a gasket or band positioned about the juncture of the pipe lines. The gasket or bands form a tight seal between the liner tube and the pipe line.
