Nor-Cal Products' Aluminum to Stainless Steel Transitions provide a reliable UHV seal for aluminum vacuum systems. An explosion bonded composite of aluminum, stainless steel and two other UHV materials make these transitions leak tight at UHV pressures. Transitions are welded to a stainless steel CF flange as a complete unit ready to weld to your aluminum chamber or beamline, or the transition can be purchased separately for welding to your own CF flange. 
  • Conflat flanges
  • Flangeless with weld prep
