Domed Blank Wire-Seal Flanges

The Wire Seal flange system is used for UHV applications.

Wire seal flanges are sexed—with male/female flanges forming a mating pair that captures an OFHC copper "o-ring" gasket under extreme compression. Standard flange sizes are 10" (254mm) to 24" (610mm) in diameter; the seal is OFHC copper wire, 0.080" (2mm) in diameter and repeatedly bakeable to 450°C.

Wire seal flanges are offered in three versions:

  • Bored ring flanges - Bored flange
  • Solid blank flanges - Flat blank flange with uniform thickness
  • Domed blank flanges - Lighter blank flange with a thick ring for bolts and seal, blanked by a domed light-gauge centerpiece

Note:
  • Since no international standards exist for wire-seal flanges of any size, we have designed ours to fit with flanges from other major manufacturers. However, you can only guarantee compatibility by purchasing both male and female flanges from the same manufacturer.
