Packing type 641

Packing braided of natural cotton saturated with special PTFE-based impregnate, thread by thread, during braiding process. The impregnate has a double function: it reduces friction coefficient while increasing chemical resistance of the packing. At the same time delicate cotton fibres make the resulting packing exceptionally soft and fitting well in the stuffing box.
General purpose packing. Recommended for use in stuffing boxes of pumps and fittings, in all sectors of industry, and in municipal economy. Resistant to water, oils, liquid fuels, lubricants and solvents, as well as to water solutions of salts and medium strength acids and bases.
