Nuclear Spiral Wound Gasket

>It is one of the most innovative and creative gaskets.
>The graphite filler is nuclear grade flexible style.
>Sealing capability is ≤1×10-7Pa•M3/s

Typical Applications
"ZERO" leakage gaskets provide the most effective sealing, the most reliable operation and he largest security assurances for middle and high pressure, high temperature or (and) fluctuation temperature, containers with nuclear safety level, equipments, valves, piping flange connecting.
Cooling water, steam, boric acid, air, nitrogen, demineralized water, oil, oxgen, 30% sodium hydroxide solution, and 7% nitric acid solution.
