Straight Reducer Nipples

We fabricate these CF nipples (spools) 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 Nipples Feature:

  • Half nipples feature one fixed flange (either tapped or through-hole bolt holes)
  • Full nipples feature one fixed and one rotatable flange (through-hole bolt holes)
  • Conical and straight reducer nipples adapt two different flange sizes
  • Common lengths and tube diameters listed
