Graphite PTFE Packing with Aramid Fiber Corners 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.
Aramid fiber packing braided from high quality Dupont aramid and kevlar fiber with PTFE impregnated and lubricant additive. It is wear resistant but may damage the shaft is not used properly. A minimum shaft hardness of 60HRC is therefore recommended.
