Asbestos Fiber Impregnated with PTFE Braided Packing

Application
NES 2500 is constructed from high quality raw materials.Selected long Canadian white asbestos fibers are injected with PTFE particles and then each strand is individually treated in PTFE dispersion. Equal distribution of PTFE lubricant effectively seals the asbestos fibers, and due to PTFE’s chemical inertness and low coefficient of friction, this creates an ideal multi-purpose packing. A general service packing for all rotating and reciprocating pumps, mixers and valves sealing against hot and cold water, ammonia, caustics, mild acids, difficult chemicals, air, gases, steam, solvents, oil and most marine applications.

All Products have ISO 9002 Registration.
