Seal Components

A male and female flange compress a 0.080 inch diameter OFHC copper wire to effect a seal. Gasket flow is confined by the geometry of the flange surfaces to the area of the seal. Minor nicks and scratches within this contact area are filled with crushed copper wire providing a seal that is leak tight at 10-13 Torr after repeated bake out to 450°C. Bolt sets are available for all size flanges from 12" to 27".
