Packing braided of aluminosilicate yarn on the pilot of glass impregnated with a special composition on the basis of PTFE. As a result, we obtained a packing which is very attractive pricewise, for operation applications. Impregnation of each thread during the process of intertwining causes very precise saturation of packing with impregnant.
It is recommended in low-and average-pressure fittings and in static applications. It may work in contact with steam, solutions of salt, acids and alkali except for concentrated ones.
