The CF Tee is a CF vacuum fitting designed for tee-type branching in high and ultra-high vacuum systems. The catalog specifies a configuration with one fixed and two rotatable flanges (one on each axis), which supports easier alignment during assembly. It offers a pressure range of 1 × 10⁻¹² mbar to ambient pressure, tightness of ≤ 1 × 10⁻¹⁰ mbar l/s, and a bake-out range up to 450 °C. It is available in Stainless Steel 304 / 1.4301 and Stainless Steel 316L / 1.4404, with standard sizes from DN16 to DN160, while custom lengths are available upon request. The tube surface is specified as glass bead blasted, with a polished version available on request.
