Product Description
Expanded Flexible Graphite ring is compressed by Expanded Graphite. It is used as sealing gasket, packing in all kinds of valves and pumps. These rings possess good resilience and chemical stability to be able to provide effective sealing function. Besides, Expanded flexible Graphite Ring can be used together with other end ring. They are very stable and reliable, even if under awful working circumstances. Frequently they are used with reinforced expanded graphite rings forming a complete set. Expanded flexible graphite ring can be used in pumps, valves, expansion joints and other parts of the seal, in the petroleum, chemical, instrumentation, thermal power, shipbuilding, nuclear power, aerospace and other fields. Also we can make them as the customers' drawings or specifications.
