GRAPHITE PACKING – BEST CHOICE FOR HIGH TEMPERATURE AND HIGH PRESSURE APPLICATIONS
Graphite Packing is made of reinforced graphite. The reinforcing materials are various fibers or wires including steel wire, copper wire, nickel wire, carbon fiber, pre-oxidized wire, glass yarn and other reinforced graphite wire.

Graphite packing resists all chemicals across the entire pH range (except fuming sulfuric acid, aqua regia, fuming nitric acid and fluorine). It also has great lubricity and excellent thermal conductivity.

It is widely used in acid and oil production industries Its resilience makes it the perfect sealant for the fuel, chemical, and gas industries.
