  • Extremely high surface finishes attainable.
  • No indents/marks in the sealing area.
  • No longitudinal draw lines that would introduce a leak path.
  • Good straightness over entire length.
  • Material waste is minimal. The part is formed from pure kovar round wire. No machining (no waste) or secondary used.
  • Highly toleranced dimensions are precisely controlled for reduced variation (ie: high CpKs).
