Trelleborg Teguflex W DW Flanged Rubber Flexible Connectors
Key Information
Trelleborg Teguflex W DW bellows are a heavy-duty moulded rubber expansion joint specifically designed for potable water and building service applications involving contact with drinking water up to 23°C. Constructed with a fluted EPDM inner tube approved to ACS, WRAS and AS/NZS 4020 standards, nylon cord reinforcement, and a weather resistant EPDM outer cover, it is engineered to absorb vibration, reduce pressure surges, compensate for thermal expansion and correct pipeline misalignment in water distribution and HVAC systems. Featuring an extended body design for increased axial, lateral and angular movement capability, the Teguflex W DW is particularly suited to larger bore pipework and installations requiring enhanced flexibility. The unit is available with a range of flange materials including zinc plated carbon steel and stainless steel, with optional vacuum rings, flameguards and PTFE safety shields available for additional operational protection. Approved for drinking water applications and manufactured in accordance with PED requirements, the Teguflex W DW provides a durable and reliable solution for larger potable water piping systems operating between -25°C to 90°C.
