Gland Packing
Phenolic Packing
Phenolic fiber packing is heart-braided from high-performance phenolic fiber impregnated with a special lubricant, then re-impregnated with high-quality PTFE emulsion during braiding to improve lubrication. A high-performance, multi-purpose general packing for pumps and valves, used in paper mills, stock pumps, hydrapulpers, refiners, wastewater and sewage plants, ships, dewatering pumps, power plants and mixers. Suitable for water, steam, brine, acid, dilute alkali, general chemicals, solvents and petroleum.
