Our flanges are made from 304 stainless steel material, which is specially processed to reduce impurities, grain size and microscopic leak paths. They are available in all commonly used high and ultra-high vacuum flange types, including ASA, NW (ISO-KF), ISO, CF and wire seal flanges. We also offer EVAC clamps and metal seals to convert a high vacuum NW flange to ultra-high vacuum.
Fittings are available with or without flanges. Weld fittings (without flanges) are typically sold to mechanical contractors for use during the fit up phase of new fab construction.
Nor-Cal Products provides a broad range of adapter fittings in order to connect two dissimilar types of components. They are made from 304 stainless steel and are TIG welded, cleaned and leak checked
for vacuum service.
Flexible stainless steel hoses are available in three thicknesses to accomodate many applications and bend radius requirements.
Nor-Cal’s flexible couplings have more convolutions than comparable products, resulting in greater flexibility and lower spring rates. Plasticized PVC hoses can be used as a low cost rough vacuum line.
Our 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. Types include thermocouple, instrumentation, medium current, high
current, BNC, and MHV feedthroughs.
Nor-Cal Products’ liquid and liquid nitrogen feedthroughs are available with or without industry standard Cajon, VCR or Swagelok fittings.
We offer a complete line of UHV compatible flanged viewports, weld stub viewports and viewport shutters. Shutters prevent buildup of process materials on the inside of the viewport window. Glass adapters are useful for mounting glass accessories to metal high vacuum systems, or to attach flange mounted components to glass systems.
