Graphite Die Formed Packing Rings
Die formed graphite packing rings are made from pure flexible graphite and die formed into rings of specific dimensions. Densities ranges from 1.6g/cm3 to 1.8 g/cm3 depending on application requirements. They may be inserted with wire mesh or stainless steel insertion for higher dynamic loading and better handling. The product displays all the characteristics that make graphite such an excellent choice as a sealing material in both static and dynamic applications. It is very suitable for use in high temperature and pressure valves and pumps. They are manufactured to allow ease of fitting and they compress easily to take up the fitting space on the valve spindle or gland housing.
