LFT/LNFT Fluid Feedthrough Configurator

KJLC Fluid and Liquid Nitrogen (LN2) Feedthroughs are constructed in order to easily allow the passage of fluids into a vacuum environment for open or closed loop systems. KJLC feedthroughs are UHV welded to the customer specified flange and come in a variety of tube diameters and termination types. LN2 feedthroughs offer an additional tube section which acts as an extended thermal path, reducing ice buildup or condensation that could occur on the atmospheric side of the flange. Custom configurations available upon request.
