Teflon® expansion joints are always fixed dimension. They are molded in two, three and five arch configurations. Series 800 is particularly popular in the chemical industry where they provide excellent  service in relatively low temperature, low pressure systems. Standard construction includes control rods as illustrated, and all sizes through 12 inch (305mm) diameter are kept in stock.
