Ring Joint

Ring Joint Gasket

is the sealing gasket of various forms processed from the solid metals of various materials through mechanical cutting by high precision CNC lathes. Featuring small installation area and high pretension pressure, they are applied in sealing parts of pressure vessels, valves and cylinders in the environments of high temperature, high pressure and high corrosiveness.
Gasket Types:

  • Flat gasket
  • Oval ring joint gasket
  • Octagonal ring joint gasket
  • RX metal gasket
  • BX metal gasket
  • Lens gasket
  • Metal gaskets in special shapes
