3-year no leakage promise, long cycle reliable sealing
　　It is with independent but homocentric stainless steel board packed graphite of weave shape and with PTFE closely attched in the flange surface. When flange being pressed tightly, the stainless steel weave graduates to be flat to wrap the sealing materials. Therefore the two surfaces of flange all reach highly effective sealing effect to protect sealing materails from being oxidated nor eroded by air and to achieve long cycle reliable sealing.
