Hand wound EPDM double ball rubber expansion joint Axial/Horiz./Angular Movement

Product Description:

Movement capability is a key aspect of any expansion joint, and Liwei's hand-wound double-ball flexible rubber joint excels in this area. Designed to accommodate axial, horizontal and angular movement, it is ideal for pipelines that change position due to thermal expansion, ground settlement or seismic activity. This flexibility not only helps prevent system failures and leaks, but also extends the life of the piping infrastructure.
