Description:
Style 649 is a braided packing made of carbon fiber which is impregnated with PTFE
dispersion. 649 is inert to almost all corrosive chemicals.
When it is used for pumps, frictional heat is freely conducted to the stuffing box metal because of its excellent thermal conductivity. As a result, no or little damage will be caused to the shaft sleeve or to the packing.
Although similar in cost, It can replace common non-asbestos (graphite/PTFE)
packings, it will last longer and handle a wider range of applications.
This unique packing is an inexpensive version of high grade carbon packings. It
can be used to replace both low cost graphited non-asbestos packings and in many cases
can be used to replace the expensive carbon packings used as end rings in valve
applications: (as long the temperature is less than + 662 degrees F).
It can be used to seal corrosive fluids except strong oxidizer acids, organic solvents. Ideal for use in centrifugal pumps, plunger pumps, mixers valves, etc.
