We fabricate these CF crosses and cubes 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 Crosses & Cubes Feature:
- One rotatable flange on each axis (crosses only)
- Through-hole bolt hole flanges (crosses only)
- Tapped sides (cubes only)
