Category: Liquid Vacuum Feedthrough

Liquid Feedthroughs
Liquid feedthroughs are a cost effective and reliable way to introduce water into a vacuum system. Tubing is .25 and .375 inch, 304 stainless steel with CF or KF flanges. They are available without fittings or terminated with industry standard Swagelok or Cajon VCR fittings. Maximum bakeout with CF flanges is 450°C and 200°C with KF flanges.

Liquid Nitrogen feedthroughs
Liquid Nitrogen feedthroughs are constructed with single and dual coaxial tube geometries. This thermal barrier effectively reduces condensation and ice build-up 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.
