NICHIASU GR Vortex gasket TOMBO 1834R-GR-EEE 20K250A

[Features]
● This gasket is made by alternately winding a hoop-shaped metal plate and GRASEAL with excellent sealing properties.
●Due to its unique structure and the properties of the Fura Seal filler, it exhibits excellent sealing performance even under severe conditions such as high temperature, high pressure, extremely low temperatures, and heat cycles.
●Because it fits well with the flange, it can be sealed with a lower tightening force than a metal gasket.

[Use]
●It can be widely used as a flange gasket for various pipes and equipment.
●Places where strict sealing performance is required, such as gas fluids.
● Corrosive fluids. (excluding oxidizing acids, oxidizing salts, halogen compounds, and combustion-supporting gases)
