Tied Lateral single/universal expansion joints that use tie rods and washer nuts to restrain the pressure thrust forces represent the simplest design of lateral expansion joints. They are suited to compensate for movements in any direction perpendicular to their axis.

For higher pressure conditions, the use of a cardanic universal expansion joint is recommended. This type of expansion joint uses tie bars with cardanic hinges to restrain the pressure thrust. They too are suited to compensate for movements in any direction perpendicular to the expansion joint axis. Another alternative is the installation of double gimbal expansion joints or two gimbal joints in a two pin gimbal system if the compensation of movements in various perpendicular directions is required. Expansion joints that are suited to compensate for lateral movements are also used to decouple pipe systems from the vibration that is generated by pumps, compressors or other engines.
