Tees

CF 2.75″ × CF 1.33″ reducing tee

T-0275-133: 2 × CF 2.75″ (DN40CF), 1 × CF 1.33″ (DN16CF) ConFlat flanges, 125.8 cm³ of internal volume and 151.2 cm² of wetted surface.

Build a system with this part

Its internal volume and surface area feed the pumpdown simulation, and its measured transmission probabilities set its molecular conductance in the pumping-speed simulation.
