SYGEF ECTFE Flare transition fitting SDR21

  Datasheet (PDF)

Georg Fischer SYGEF ECTFE flare transition fittings provide an ultra-pure, chemically inert transition between rigid metric ECTFE piping networks and flexible fluoropolymer flared tubing lines. Engineered for rigorous high-purity fluid handling and demanding chemical distribution environments, the component features an SDR21 geometry rated for continuous operating pressures up to PN10 (10 bar). One end is constructed with a calibrated spigot designed for seamless infrared (IR) welding as well as conventional butt fusion, guaranteeing full cross-sectional alignment, laminar flow characteristics, and minimal bead formation to eliminate dead zones where contaminants could accumulate. The opposing terminal integrates a precision-machined mechanical flare transition that securely mates with fluoropolymer process tubing in fractional dimensions including 1/4 inch, 3/8 inch, 1/2 inch, 3/4 inch, and 1 inch across metric pipe diameters d20 (DN15), d25 (DN20), and d32 (DN25). Molded entirely from high-grade ethylene chlorotrifluoroethylene, the fitting exhibits outstanding barrier resistance against chemical permeation, severe abrasion, concentrated inorganic acids, aggressive alkalis, and halogenated oxidizing agents typical of semiconductor fabrication, wet bench manufacturing, pharmaceutical synthesis, and industrial chemical dosing plants. The flare compression mechanism generates a robust, vacuum-proof, and hermetically sealed fluid path without requiring secondary elastomeric O-rings or adhesive compounds, ensuring complete system purity and eliminating the hazard of media contamination. With an extended spigot length (L2 of 30 mm), this transition fitting offers ideal clamping and alignment stability within automated cleanroom welding equipment, including Georg Fischer IR-63 M and IR-110 fusion apparatus, delivering durable, repeatable joint integrity in critical clean media installations.
