Pilotgraph 4001 Packing

Pilotgraph 4001 Packing

• Long sealing life for high temperature high pressure applications
• Inclusion of a corrosion inhibitor ensures stainless steel shafts do not suffer pitting
• Manufactured from highest quality pure graphite with minimal impurities
• High Thermal conductivity and low friction properties ensure increased service life
• Easy to cut and install so can be used to replace moulded rings resulting in greatly reduced stock and cost

Manufactured from very pure expanded graphite containing minimal amounts of trace elements such as sulphur and chloride. This ensures that the packing has high thermal conductivity, very low friction and rapid heat dissipation, factors that ensure a long seal life. The inclusion of a corrosion inhibitor ensures that when the packing is used on components with stainless steel stems, pitting does not occur in environments prone to galvanic corrosion.

Pilotgraph 4001 is excellent packing for use on rotating pumps, reciprocating pumps and valves on hot oils, hydrocarbons, chemicals, solvents, steam (saturated & superheated) in refineries, petro chemical, power generation and metal processing industries.
