Wire Seal Flanges

Introduction


MDC Wire Seal Flanges provide a convenient method of metal-sealing relatively large diameter vacuum chambers. These metal seal flanges pick up where the Del-Seal™ CF flanges Del-Seal™ CF metal seal flanges leave off. 

Applications include bell jars, vacuum furnaces, and a variety of other ultrahigh vacuum enclosures. All MDC Wire Seal Flanges are made of 304ss material. To make the seal, an .080" cross-section diameter OFE copper wire gasket is compressed between mating male and female flanges. The geometry of the beveled sealing surface confines the flow of the crushed gasket material, causing it to fill in minor nicks and scratches in the seal area. These flanges can also be used with elastomer gaskets.

Wire Seal Flanges

MDC Wire Seal Flanges provide a convenient method of metal-sealing large diameter vacuum chambers. These metal seal flanges pick up where the Del-Seal™ CF flanges Del-Seal™ CF metal seal flanges leave off. They are available for tube sizes from 10 to 24 inch diameter, and only in a nonrotatable geometry. Because of their size, blank wire seal flanges are of significant weight. For applications restricted by weight limitations MDC offers blank wire-seal flanges with a dished-head construction which greatly reduces the flange’s overall weight.

An .080 inch cross-section diameter OFE copper wire gasket is compressed between male and female mating flanges. The beveled geometry of the sealing surfaces confine the flow of the crushed gasket material, causing it to fill minor imperfections in the seal area. See the wire seal flange cross-section diagram at the bottom of the previous page. Applications for the use of wire-seal flanges include bell jars, vacuum furnaces and a variety of other ultrahigh vacuum enclosures. As with Del-Seal™ CF flanges, these too can be used with elastomer gaskets for high vacuum applications.
