CHESTERTON TYPE TWO - GLAND PACKING

Specification of CHESTERTON TYPE TWO - GLAND PACKING

Two

High Speed Graphite

Chesterton Two high speed graphite packing is manufactured from a pure quality

graphite yarn braided in interbraid construction, then treated with special, high

temperature, break-in lubricants. The special sacrificial multi-temperature lubricants

are used to ease break-in and quickly effect a satisfactory leakage rate. Once the

break-in lubricants are sacrificed, the remaining super-graphite product has the

chemical resistance to withstand virtually all chemicals. The highest conductivity

of this packing combined with the automatic self-lubricating properties allow use

with virtually no shaft scoring.
