Swivel joints can be fitted to fixed piping used to transport liquids and gases in order to add flexibility. The spring-energized seals in the WLT swivel joints guarantee a perfect sealing under all operating conditions (high pressure, high and low temperature). The three-part design of the WLT swivel joint makes that the product seals can be replaced without removing the bearings. The leak detection indicates the condition of the seal.
The swivel joints are available in several versions and materials.
