PV V&E's line of gas vacuum feedthroughs includes the most commonly required for medium, high, and ultra-high vacuum applications and are available without fittings or terminated with industry-standard Swagelok or Cajon VCR fittings. Maximum bakeout with CF flanges is 450ºC and 200ºC with NWs. Vacuum ranges are 10-10 mbar and 10-8, respectively.
Liquid nitrogen feedthroughs are constructed with single and dual coaxial tube geometries. This thermal barrier effectively reduces condensation and ice buildup on the atmosphere side of the feedthrough around the mounting flange interface, protecting the seal’s integrity. This is necessary because of the extreme thermal gradients encountered with liquid nitrogen. Swagelok stainless steel tube compression fittings provide a leakproof, torque-free vacuum seal by swaging the stainless steel tube to which they are mated. Our fittings require no gaskets. Cajon VCR stainless steel compression fittings provide a quick and efficient means of vacuum system assembly. These zero-clearance fittings make them the perfect installation solution when space is limited. The compression of a removable copper gasket creates a vacuum seal between the air and process sides.375 (6.35 and 9.53mm) inch OD, 304 stainless steel with CF or NW flanges. They are available without fittings or terminated with industry-standard Swagelok or Cajon VCR fittings. Maximum bakeout with CF flanges is 450ºC and 200ºC with NWs. Vacuum ranges are 10-10 mbar and 10-8, respectively.
