Holtec Metal O ring

Stainless Steel or Inconel tubes are formed into an O ring shape, the ends are welded together, and then surfaces are finished ultra-smooth.

PTFE coating or silver plating is used on the surfaces for sealing gases, vacuum and highly volatile liquids. Highly reliable sealing performance is provided over a wide range from high temperature to cryogenic temperature, and from high pressure to vacuum.

This gasket features a compact design that requires a comparatively low seating stress and requires little space
