The CF Reducer Tee is a CF vacuum fitting designed for branch connections where one flange size is reduced to a smaller connection size within a tee configuration. The catalog specifies one fixed and two rotatable flanges (one on each axis), making alignment easier during installation. 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 several main flange and reducer flange combinations. Custom lengths are available upon request, and the tube surface is specified as glass bead blasted, with a polished version available on request.
