We offer the full range of Nor-Cal products, including high vacuum and ultra-high vacuum flanges, valves, fittings, foreline traps, feedthroughs, manipulators and heater jackets. 

 
The Nor-Cal range has been designed to cover a wide variety of vacuum applications across multiple industries. Wherever they are used, our components offer levels of performance and reliability unrivalled by any other manufacturer. Our policy of continual investment into research, development and manufacturing has enabled us to offer high quality vacuum components that set the standard for all others to follow.
 

The latest, state-of-the-art machinery has also enabled Nor-Cal to drive down costs of production, resulting in better value for our customers. 

 
In the sections below you’ll find a general overview of the products and services offered by Nor-Cal UK Ltd. If you would like to find out more, please visit our website or contact us on 01666 861221.

Chambers & Weldments

Nor-Cal has a worldwide reputation for quality – a reputation that is fully justified. The quality, appearance and performance of our high and ultra-high vacuum chambers are unequalled anywhere in the industry. Whether you require a one-off chamber for a university or large volumes for original equipment manufacturing, we can provide a solution that meets and exceeds all expectations. Nor-Cal also offers a complete line of vacuum chamber accessories, including load locks, sample transfer and positioning devices, liquid and electrical feedthroughs, viewports and roughing components. 

 
Cylindrical and rectangular chambers can be made up to approximately 5ft square with doors, stands, water jackets and Mumetal shields. 

Isolation & Control Valves

Nor-Cal supplies an extensive range of isolation and control valves that offer outstanding performance in even the most demanding applications, including semiconductor and compound semiconductor processing. This includes both manually and pneumatically actuated models with die-formed, 304 grade stainless steel bodies and electropolished surfaces for faster pump-down, lower outgassing and improved corrosion resistance. For more details and specifications, please visit Nor-Cal UK online or get in touch on 01666 861221.

Foreline Traps & Filters

Nor-Cal has been designing and building standard and bespoke foreline traps for the vacuum industry since 1962, making us one of the most experienced manufacturers in the market. Nor-Cal Traps range in complexity from the sealed coaxial type (which prevent oil backstreaming) to the triple-pass water cooled variety (which remove condensable gasses that contaminate mechanical pump oil or other parts of the system). On average, our customers see a 200% improvement in preventative maintenance intervals after installing one of our traps. With exception to our sealed coaxial metal sieve traps (which have a one-piece body), all of our traps are designed to be easily disassembled for cleaning, maintenance or replacement.

Flanges & Fittings

Nor-Cal’s range of CF flanges are available in sizes from 1? to 16 ½ inches OD for ¼ to 14 inch tubes. All of them are compatible with other Conflat® style flanges. Nor-Cal uses state-of-the-art CNC machining techniques to produce flanges of exceptional quality. They are machine washed in an approved aqueous detergent after machining, and can also be chemically cleaned if required. To find out more about our CF flanges, please visit Nor-Cal UK online or get in touch on 01666 861221.

Weld Fittings

Nor-Cal has been manufacturing stainless steel weld fittings for more than 40 years, and we utilise all of this experience to produce high quality, made-to-measure components suitable for even the most demanding of applications. Weld fittings are often used in vacuum roughing lines on semiconductor process equipment, as well as in forelines and pump exhaust lines in semiconductor subfabs. Pulled-port welding techniques and full penetration butt welds ensure a crevice-free joint and a high level of cleanliness for UHV applications. Most weld fittings are made from 304 grade stainless, though some sizes are stocked in 316L for enhanced corrosion-resistance.

Thermal Products

Nor-Cal UK offers an extensive range of heater jackets, controllers and accessories. Our heater jackets offer a tight contact fit, trimable materials, are constructed of silicone rubber and provide even heating up to 200°C. The jackets have been specifically designed to significantly enhance vacuum line performance and will improve heat transfer by minimizing cold spots. Our heat jackets are also designed to reduce particle generation, which leads to a reduction in system downtime. We offer a one year warranty on our heat jacket products and full details of our complete range are available on a downloadable spec sheet at the Nor-Cal UK website.

Adapter Fittings

Nor-Cal UK Ltd offers an extensive array of adapter fittings that will allow you to connect components of differing type.
