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.
Die formed graphite ring are made of expanded graphite without any filler or binders. No special corrosion protection is required. In general, it has square section and has V shaped and wedge shaped section.
Ceramic fiber is standout among the different organic and inorganic fibers as ideal replacement of asbestos. The packings are made from high quality ceramic fiber, it has excellent capabilities of high strength and high temperature resistance.
Carbonized fiber packing braided from shrink-proof synthetic fiber impregnated with PTFE, Silicone-oil-free. Oxidized fiber has high strength and good thermal conductivity, PTFE makes the packing have excellent self-lubrication.
This packing is a multi-yarns packing. The corners of packing are made of aramid fiber yarns impregnated with PTFE, the friction faces are made of PTFE yarns. This structure enhances the lubrication ability of aramid fiber and improves the strength of the pure PTFE.
The rubber core can absorb vibration to control leakage. Normally use silicone rubber core.
Nomex Fiber Packing braided from high quality Dupont Spun nomex yarns with PTFE impregnated and lubricant additive, high cross-sectional density and structural strength, good sliding characteristic, gentle on shaft. Compared to kevlar, not hurt shaft, good idea for food industries.
Spun Kevlar packing braided from high quality Dupont Kevlar fiber with PTFE impregnated and lubricant additive. Compared with other kinds of packings. It can resist more severe media and high pressure.
Spun aramid packing impregnated with graphite. No harm to shaft, still wearable, good heat conduction.
