                SPIRAL WOUND GASKET    
                 

                   Spiral Wound Gaskets can be used to seal fluid pressure up to 250 bar cryoprnices temperature as low as -200<C and up to elevated temperature of 1000<C. Products are widely used in the oil, gas, petrochemical process and engineering industries.
