CF flanges utilize an OFHC (Oxygen Free High Conductivity) copper gasket (also sold separately) for effective seal up to 1x10 Torr. Moreover, the copper gasket can sustain a temperature of up to 450°C, but reuse of copper gaskets is not recommended.

Cleaning and Packaging

All products with weld joints are 100% helium leak tested to assure leak free operation prior to use. In addition, to ensure the cleanliness of AdvanTorr products, all parts are ultrasonically cleaned to UHV standards using de-ionized water and packaged in contamination free, class 10,000 clean room conditions. Each bag is affixed with a barcode label identifying the component's part number, heat number and batch number for full traceability.
