Tees (PN 10) The one-piece excecution with PFA assures a perfect ow in the base body and at the outlet. The manufacturing of our PFA-Tees is done by injection moulding (Extruder). For tees with nominal widths larger than DN 100, we rely on our approved paste liner. Both manufacturing technologies assure a specially smooth and easy-to-clean surface.
