Notable Features: 
  • Very large volume head combined with small diameter shaft.
  • Very high surface finish no machining lines or machining tit present at either end of the part.
  • Very good surface finish present on the sealing surfaces. No leak paths.
  • Material waste is minimal.
  • Normally, this component is a machined part are turned from large diameter bar stock on a screw machine. Sussex Wire forms this from coiled wire and forms it into the current shape with no material waste.
  • Production speeds are high allowing for low production costs. Much faster than machining.
  • Concentricity of all diameters is near perfect: TIR approx. .002".
  • Surface finishes are smooth for good hermetic sealing characteristics. No machining marks/spirals/inclusions are present.
