Larson Electronic Glass’s industry standard CF-type UHV
flanges offer reliable sealing performance as result of
the design geometry which “captures” the gasket
These CF flanges have a conical sealing edge that is
pressed into the top and bottom surfaces of an OFHC
copper gasket, a lateral cold flow of the gasket occurs.
This cold flow is limited by the vertical flange wall.
Further material flow is severely limited and high
interface pressures are developed. These pressures cause
gasket material to fill surface imperfections and
produce a highly reliable seal. At high temperatures,
the “capturing” geometry maintains high pressure despite
of the gasket material softening.
