Standard Tee

We fabricate these CF tees for UHV systems from 304L stainless steel tubing and knife-edge (ConFlat) flanges. The CF flange is the most widely used for high vacuum and UHV applications. Many gauges, instruments, accessories and feedthroughs are available on this flange system.

CF Tees Feature:

  • One fixed and two rotatable (one on each axis) flanges
  • Through-hole bolt hole flanges
