Wire Seal

Wire Seal Flanges & Fittings

Ebara wire seal flanges are designed for use on bell jars, custom vacuum chambers and related systems. Standard sizes range from 12 to 27 inch nominal OD for tube sizes from 10 to 24 inch OD. 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. Solid blanks are standard. Dished head blanks are offered as a lower cost alternative.
