V-flex expansion joint

V-flex expansion joints are flexible connectors that absorb multi-directional (X, Y and Z axis) stresses in pipelines caused by earthquakes, settlement, thermal expansion and structural movement. They provide FM-approved solutions, especially at building expansion joints and in fire protection lines.
