  • Flexible replacement section for irrigation and water pipe
    Patent number: 5778935
    Abstract: For connecting the spaced ends of underground irrigation or water pipe, a flexible replacement section with a rigid tubular coupling at each end is employed. Each coupling has an inner diameter equal to the outer diameter of the pipe being connected and is adapted to receive a pipe end therein. After one coupling is aligned with and mounted on one of the pipe ends, the replacement section is flexed so that the other coupling can be aligned with and mounted on the other pipe end as the flexed section is straightened.
