GrafSeal Packing are recommanded for use in valves and pumps handling heat transfer fluids, ols, acids, alkalies, solvents, hot water, boiler feed water, hydrocarbon products as well as super heated high pressure steam. Grafseal Packings are excellent for Nuclear Services. The "Chloride content" of this packing is kept much below the permissible values. In radiation atmosphere, especially the packing mechanic will be able to spend limited time for packing valves and pumps. Precision moulded packing will therefore be safer and advantageous. Grafseal Packing Rings are supplied in three forms, endless, split and in two halves.
