Detailed

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

 

Applications

Valve bonnets, high pressure vessel flanges, equipment joints, pipe flanges, plastic precessing machinery, hydraulic equipent, pneumatic equipment, vacuum vessels, nuclear power containers, aircraft engines, rocket engines and automobile engines
