Daiko graphite spiral gasket (SS400) Nominal diameter (A): 250

[Features]
● High-performance semi-metallic gasket designed for high temperature and high pressure.
●Since it is not easily affected by temperature changes, it exhibits excellent sealing performance even under severe heat cycle conditions from high to low temperatures.
●No need to control the tightening surface pressure like a joint sheet.
● This is a spiral gasket that uses graphite (expanded graphite material) tape as a filler material.

[Use]
●Flange joints for high temperature and high pressure from general piping.
●Various industrial flange connection points such as steam pipes.
●Cryogenic flanges especially for high-temperature/high-pressure steam, LNG, liquid nitrogen, liquid hydrogen, etc.
