This is a genuine Trelleborg Teguflex® Flexible Expansion Joint Bellows (DN80 / 3-inch nominal bore), engineered for commercial pumping stations, district heating setups, HVAC building services, and industrial process piping loops.
Designed to absorb axial, lateral, and angular thermal expansion while dampening high-frequency mechanical vibration from centrifugal pumps, chillers, and turbines, this heavy-duty expansion joint protects piping networks from fatigue failures. Featuring turnable zinc-dichromate plated carbon steel backing flanges stamped S235JR for easy bolt alignment, this unit is certified to European Pressure Equipment Directive (PED 2014/68/EU) standards.
Genuine Trelleborg OEM Quality: Premium industrial expansion joint from Trelleborg Industrial Solutions.
Effective Noise & Vibration Isolation: Actively dampens high-frequency mechanical vibration and acoustic noise generated by inline pumps, compressors, and chillers.
Swivel Flange Design: Features turnable/rotatable zinc-dichromate plated carbon steel backing rings for effortless bolt-hole alignment during retrofits and new installations.
PED (2014/68/EU) Certified: Fully compliant with European Pressure Equipment Directive safety standards, featuring factory-moulded identification compound indicator bands.
Versatile Fluid Application: Ideal for cooling water loops, HVAC systems, salt water line isolation, district heating, and mild chemical processing networks.
