CF 13.25″ to CF 8.0″ zero-length reducer

1 × CF 8.0″, 1 × CF 13.25″ (DN250CF) ConFlat flanges, 577.4 cm³ of internal volume and 647.4 cm² of wetted surface.

Build a system with this part

Its internal volume and surface area feed the pumpdown simulation, and its 3D characterization sets how it affects pumping speed.
