SUNWELL SW610 Zero leakage gasket is composed of stainless steel fixed inner and outer ring as well as industrial grade and unclear grade flexible graphite sealing rings which are specialized making. It's one of the most innovative and creative gaskets. Our idea of creative design conforms to occasions which with sudden change of temperature and fluctuation pressure.

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.
