CF Reducing Nipples

Conflat, CF reducing nipples with a rotating flange on one end of a straight tube and a non-rotating flange on the other end. Both flanges have clearance holes, not threaded, for mounting bolts. The tube and the flanges are made from 304 stainless steel. The tube is port-pulled and bead-blast finished for improved cleanliness.

Vacuum range is > 1x10 E-13 Torr for ultra high vacuum, UHV with a metal C-seal. With an elastomer seal vacuum range is > 1x10 E-8 Torr, high vacuum, HV applications.

Bakeout temperature is up to 450 degrees C.

Upon request CF reducers are available in 316L stainless steel for added corrosion resistance.
