High-Performance Electrical Feedthroughs, Water-Cooled Feedthroughs, and More

Vacuum feedthroughs are used to transmit water, voltage, or currents between components in a vacuum system. NorCal Products, Inc. dba Pfeiffer Vacuum Valves & Engineering carries an extensive line of liquid and electrical feedthroughs manufactured to quality standards. Our product line consists of commonly required feedthroughs for general vacuum applications, with materials ranging from aluminum to 304 stainless steel. Custom designs or modified standards can readily be supplied upon request.

Advanced Vacuum Feedthrough Technology

Power Vacuum Feedthroughs

Our robust ceramic to metal feedthroughs have electrical ratings for operation, with one side in dry atmosphere while the opposite end is fitted in a stable vacuum. Applications include ultra-high vacuum systems with CF flanges or high vacuum systems with NW flanges. Materials include high alumina ceramic insulators, OFHC® copper and nickel conductors, and 304 stainless steel flanges.

High Voltage Ceramic Break Insulators

Vacuum insulators (breaks and isolators) electronically isolate one component or system in your vacuum from another. Maximum voltage for insulators is 3KV015KV, depending on size. Our ceramic insulators are UHV compatible.

Thermocouple Vacuum Feedthroughs

Thermocouple feedthroughs carry instrumentation signals while providing electrical isolation and hermetic sealing. Insulators are made of high purity, high strength, low-loss alumina ceramic, and feature -20°C to 150°C elastomer seals.

Instrumentation Vacuum Feedthroughs

Our 8 pin, 2 amp instrumentation feedthroughs transmit signal voltages and currents. Process control in surface analysis, electron microscopy and electron beam evaporation are typical applications. Multi-Pin, BNC Coaxial, and MHV Coaxial feedthroughs are available.

Liquid / Gas Vacuum Feedthroughs

Single and Dual tube feedthroughs reduce condensation and ice buildup on the atmosphere side of the feedthrough and the mounting flange interface. Liquid / Gas feedthroughs are available without fittings or terminated with industry standard Swagelok® or Cajon® VCR tube fittings.

LN2 Vacuum Feedthroughs

Liquid nitrogen feedthroughs are constructed with dual and coaxial tube geometries to reduce condensation and ice buildup on the atmosphere side of the feedthrough around the mounting flange interface, protecting the seal’s integrity. Tubing is .25- and .375-inch OD with CF or NW flanges.

Electrical & Water-Cooled Feedthrough Applications

We manufacture custom and standard vacuum feedthroughs for medium, high, and ultra-high vacuum applications. The capabilities of each feedthrough vary based on design and materials used. While we are always looking to expand our capabilities, frequent applications for our vacuum feedthroughs include:
  • Semiconductor industry
  • Research laboratories
  • Energy and aerospace
  • Life and health sciences development
