low pressure stainless steel flexible grooved coupling(300psi)
 

housing:
stainless steel is used as raw material with good corrosion resistance. and there is the natures which is high strength, good toughness and good mechanical properties. according to the precision casting process, the precision of the clamping size is guaranteed.the material has tensile strength which is not less than 600 mpa and the extension is not less than 15%. withstands high pressure and high impact of pipeline by several disadvantage factors.

gasket :
the gasket seal with special c-shaped design, that is perfect matching with pipeline dimension in order to achieve working pressure.the gasket is tightener while further pressed in order to achieve sealing efficiency.when the meanwhile, the imported raw material will also be guaranteed the mechanical properties.
