Graphite
CONSTRUCTION
Style 2022 packing is a medium hard packing which is produced by extruding PTFE in which fine particles of graphite have been encapsulated. The packing is unsintered and is treated with a break-in lubricant to further reduce the coefficient of friction. Due to its softness, the packing prevents shaft wear and scoring and conforms easily to damaged shafts.
APPLICATION / SERVICE
Style 2022 packing can handle water, steam, oil, solvents, acids and alkalis and can be used for abrasive sludge applications. It is particularly suitable for use in centrifugal pumps, valves, mixers and agitators.
