Fundamentals # 1982 York

Sealing rings of natural and synthetic rubber have been used for connecting pipes since 1930.

The flexible rubber sealed pipes meant tighter pipe systems and easier handling of pipes at the site. This paper will describe the history of the usage of flexible rubber joints and the present trend towards prefabricated and locked-in sealing systems.
