Electrical Feedthroughs

Nor-Cal Products, Inc. extensive line of electrical feedthroughs are manufactured from ultra-high vacuum grade materials such as high alumina ceramic insulators, OFHC® copper and nickel conductors, and 304 stainless steel flanges. These robust ceramic to metal feedthroughs have electrical ratings for operation with one side in dry atmosphere while the opposite end is in a stable vacuum. They are used in ultra high vacuum systems with CF flanges or high vacuum systems with NW flanges.

CF feedthroughs can be baked to 450°C and NWs to 204°C with maximum system pressure of 1 x 10-4 Torr. Our product line consists of the most commonly required feedthroughs for general vacuum applications. Customs designs or modified standards can readily be supplied.

Liquid Feedthroughs

Nor-Cal's product line of liquid and liquid nitrogen feedthroughs includes the most commonly required for general, high and ultrahigh vacuum applications. Tubing is .25 and .375 inch OD, type 304 stainless steel with CF or NW flanges. They are available without fittings or terminated with industry standard Swagelok® or Cajon® VCR tube fittings. Maximum bakeout with CF flanges is 450°C and 204°C with NWs. Vacuum ranges are 10-11 Torr and 10-8, respectively.

Watercooled liquid feedthroughs are a cost-effective and reliable way to introduce water into a vacuum system. The .035 inch single wall tube construction is designed for the transmission of water as a cooling agent.

Liquid nitrogen feedthroughs are constructed with dual and 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, torquefree vacuum seal by swaging the stainless steel tube to which they are mated. They require no gaskets.

Cajon® VCR stainless steel tube compression fittings properly handle rapid makeup in tube, pipe and welded vacuum systems. These zero clearance fittings make them the perfect installation solution when space is a problem. Compression of a removable copper gasket creates a vacuum seal between air and process sides.
