Significant cost and safety benefits found in VITALFLEX® seismic expansion joints
•    It is an inexpensive alternative to dual-tied bellows expansion joints and especially ball joints.
•    During an earthquake, it protects equipment by allowing boilers, chillers, fan-coil units and other systems to move independently from buildings such as hospitals, high rises and stadiums
•    Installation at the connection point, prevents nozzles from cracking or shearing off
•    A break in the gas pipe work could start a fire and cause vast damage to the entire building. This Australian Gas Approval (AGA) certified seismic expansion joint will compensate for the movement that occurs during any seismic activity such as an earthquake
•    Designed for potable water applications the VITALFLEX® joint can be Watermark certified in accordance with WMTS 520:2016
