ECTFE Tee 90°

  Datasheet (PDF)

The Georg Fischer SYGEF ECTFE equal 90° tee SDR21 PN10 is engineered for high-purity distribution networks and demanding chemical conveyance systems requiring absolute chemical inertness and structural reliability. Fabricated entirely from premium ethylene chlorotrifluoroethylene (ECTFE), this equal three-way branch fitting provides exceptional resistance against high concentrations of aggressive chemicals, including strong mineral acids, caustic alkalis, oxidizers, and industrial solvents across elevated operating temperatures. Designed with a dimensional ratio of SDR21 and rated for an operating pressure of 10 bar (PN10), the fitting maintains full geometric consistency across metric outer diameters ranging from d20 mm (DN15) up to d110 mm (DN100). Each branch features extended spigot ends explicitly calibrated for non-contact infrared (IR) fusion as well as conventional butt fusion jointing methods, enabling fully automated, bead-controlled welding compatible with machine platforms such as the IR-63 M, IR-110 A, IR-110 Plus, and IR-225 Plus. This infrared jointing profile ensures stress-free, homogeneous welded transitions with minimal internal bead formation, thereby eliminating fluid turbulence, preventing bacterial entrapment, and preserving uninterrupted laminar flow dynamics during 90-degree media distribution or flow merging. The smooth fluoropolymer surface finish prevents scaling, media deposition, and contamination, satisfying the stringent cleanliness criteria demanded by the semiconductor fabrication, chemical processing, pharmaceutical, and high-purity water sectors. Engineered to withstand harsh industrial processing conditions without degradation or permeation, the component delivers long-term operational safety, hydraulic efficiency, and dimensional stability in aggressive chemical transport pipelines.
