sealing ring is a pressure assisted sealing component specially designed and customized for various supercritical fluid equipment, consisting of a non-metallic jacket and a metal spring combination.

The operating principle of the product is to select suitable inner and outer diameter sizes and metal spring styles based on the size of the sealing groove. After the product is installed in the sealing groove, the metal spring in the sealing ring can make the lip of the jacket tightly adhere to the sealing surface of the groove, forming the initial sealing force. After closing the locking device cover and starting to inject the working fluid, with the increase of supercritical fluid CO2 pressure, the sealing force generated by the sealing ring will also increase. With the dual effect of spring pressure and system pressure, reliable sealing of supercritical fluid equipment can be achieved.
