Keywords: Packing, Graphite

Construction: Multi-Lok Braid
Features: Yarns are coated in PTFE suspensoid. This system of impregnation assures even distribution of the PTFE. The fibers are saturated and sealed with the PTFE particles, protecting the fibers from chemical action.
Surface Treatment: A surface coating of PTFE is applied after braiding. To assure good break-in characteristics, a special high temperature synthetic lubricant is added.
Equipment: General service on rotary and reciprocating pumps, agitators.
Recommended For: Caustics, mild acids, difficult chemicals, air, gases, solvents, oils, general chemical plant applications.
Limitations: Shaft speeds to 1885 FPM; temperatures to 500ºF/260ºC; pH 3-11.
2225 - Same as ML2225 except square braided.


CS 2400 High Performance
Service Packing

Construction: Multi-Lok Braid
Features: A Multi-Lok braided with Sealing Equipment’s unique lubrication process that transforms each individual fiber into a reservoir of lubrication for longer packing life. An excellent high performance alternative.
Treatment: Proprietary non-petroleum lubricant containing no sulphur, silicone or wax.
Equipment: Rotating and reciprocating pumps, washer journals, liquor pumps, refiners, digesters and many other uses.
Recommended For: General surface applications where graphite may not be acceptable: steam, water, acid, chemical and solvent applications, multi-use in chemical plants and pulp and paper mills.
Limitations: Shaft speeds to 1800 FPM; temperatures to 500º/260ºC; pH 3-11 (except concentrated or hot sulfuric or nitric acid).


CS 4002 Packing

CS 4004 Yellow Jacket Packing

Construction: Multi-Lok Braid
Features: A combination braid of ML 4002 and aramid fibers. This construction provides the strength of aramid fibers and the heat dissipating and lubricating qualities of the PTFE and graphite matrix.
Treatment: Light coat of an inert break-in oil.
Equipment: Paper mill stock pumps, agitators, or any service where strength and good lubricating qualities are needed.
Recommended For: All types paper mill applications where graphite is suitable.
Limitations: Shaft speeds to 2500 FPM; temperatures to 500ºF/260ºC; pH 3-11.


CS 4800 Aramid Filament Packing

Construction: Multi-Lok Braid
Features: Non-asbestos aramid fiber.
Treatment: Each strand is individually treated with PTFE coating and a light inert oil
Equipment: Rotating and reciprocating shafts. All equipment handling tough abrasive products.
Recommended For: General service, caustics, mild acids, chemicals, air, oil gases, solvents, general chemical plant applications.
Limitations: Shaft speeds to 1900 FPM; temperatures to 500ºF/260ºC; pH 3-11.


CS 6225 Packing

Construction: Multi-Lok Braid
Features: A proprietary blend of non-asbestos yarns treated with PTFE throughout the body of the packing. The PTFE suspensoid thoroughly impregnates, seals and fills all voids providing a better resistance to chemical attach. A light lubricant is applied under pressure to improve run-in properties.
Equipment: Rotating and reciprocating pump and valve equipment, mixers and agitators.
Recommended For: Pulp and paper mill applications, recovery pumps, chemical applications, caustic soda. An excellent all-around general service chemical packing.
Limitations: Shaft speeds to 1885 FPM; temperatures to 550ºF/288ºC; pH 3-12.
Remarks: The yarns retain a greater volume of PTFE dispersion and are more uniformly distributed to provide longer and better sealing.



CS 310 High Temperature
Valve Packing

Construction: Braided Inconel wire-inserted carbon yarn over mastic core.
Features: Inconel wire-inserted carbon yarn jacket over a core of high temperature fibers and graphite. A corrosion inhibitor is added to protect the valve.
Surface Treatment: Moly coated.
Recommended For: Steam, super heated steam, air petroleum products, hot gases.
Limitations: Recommended for valve service; maximum line temperatures to 1200ºF/649ºC; pressure to 2500 p.s.i.
