Metal O-ring is made from high precision metal tube. Contrary to flat gaskets,it requires extreme low bolting load. Because it features a certain resiliency or spring back, it will compensate minor flange rotation and maintain positive sealing load to the sealing surface.
Metal O-ring is usually suit for garment,bag,handbag,purse.It also has zinc alloy rolling casting,nobleness and good quality in plating.The handles hydrogen gas up to non- Newtonian fluids.It also has moderate pressure capability, lowest leak rate, radiation resistant and so on.
Metal O-ring is made for internal or external pressure. For high pressure application it advises vented or system pressure assisted metal o rings.It is mainly used for static sealing in flange joint of high pressure pipeline, container,equipment and etc.
