This packing is a multi-yarns packing. The corners of packing are made of aramid fiber yarns impregnated with graphite PTFE, the friction faces are made of graphite PTFE yarns. This structure enhances the lubrication ability of aramid fiber and improves the strength of the pure graphite PTFE.
Multi-yarns in zebra braided packing consisting of RGS Graphite packing yarns and aramid fiber. Compared to P308B, it has excellent lubrication ability and thermal conductivity.
