Expanded Graphite Packing<\/td><\/tr>

<\/td><\/tr>

It is made of pure graphite sheet\/coiled material, and chemical and high temperature treated by natural high pure flake graphite, and die-pressed or rolling pressed, with no bonding adhesive. Under the brash working condition. It will still have a good sealing performance, with long lifespan, and low maintain cost.<\/P>
