Dynamic Flow manufactures large range of ring gaskets in accordance with API-6A & ASME B16.20, as applicable. We manufacture four basic types of ring gaskets; octagonal shape, oval shape, type RX and type BX. The dimensions are standardized and require specially grooved flanges. The octagonal cross section has a higher sealing efficiency than the oval and would be the preferred gasket. Stock materials include low carbon steel and SS316L.
