Radius 90° ConFlat® (CF) UHV Elbows

We fabricate these CF elbows 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 Elbows Feature:

Radius or miter design
Both flanges rotatable with through-hole bolt holes
