Expansive graphite packing ring

Expansive graphite packing ring is a kind of ring packing, made of flexible graphite paper, which is pressed through the spiral winding in the mold after cutting. Generally the section is square. It also can be wedged into a V shape. The latter two types are applicable for the high pressure position.

Performance and characteristic::
1. Good self-wetting property
2. High rebound coefficient
3. It can be beveled by a 45° cut according to the customers' demand.
