Wire Seal Bored & Blank Flanges

Pfeiffer Vacuum Valves & Engineering's wire seal flanges are designed for 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 0.080-inch thick OFHC copper wire is compressed between the two flanges to effect a robust UHV seal. Solid blanks are standard. Dished head blanks are offered as a lower-cost alternative.
