High-Performance, Non-Staining, Multi-Purpose Packing for Demanding Applications
A reliable sealing solution can save you both time and money on your pump operation. Traditional braided pump packing requires frequent gland adjustments and often burns out quickly, especially under high speeds. This results in packing failure and equipment damage.
Chesterton® DualPac 2212 is created using the patented DualPac Technology, which combines a burn-resistant material on the packing’s shaft side with a highly resilient outer fiber. This formulation creates a unique, long-lasting packing that uses the gland load more efficiently and achieves a reliable and quicker break-in period. This ability keeps the packing internally loaded against the rotating member while, at the same time, resisting burning and shaft scoring. DualPac 2212 gives users peace of mind in the toughest sealing applications.
DualPac Technology Advantages:
Significantly fewer gland adjustments than traditional packing
Simplifies your inventory: you can use the same packing for end rings and sealing rings
Better utilization of gland load in sealing configuration
Thermoset Fiber for Plant-Wide Use in Pumps and Rotating Equipment.
Chesterton 1730 Mill Pack™ thermoset fiber packing provides outstanding heat resistance while maintaining excellent leakage control and reduced power consumption. Rugged, easy-to-use thermoset fiber packing controls leakage effectively while it is kind to shafts. 1730 Mill Pack provides high reliability in the most demanding applications. It is resistant to heat and will not glaze like common paper mill packing, even at high shaft speeds.
Unique to Chesterton, 1727 Multi-Lon® is a synthetic packing designed specifically for general service pump applications. It is able to deliver performance equal to synthetics with the pliability of asbestos. Unlike the first generation of synthetic packing, Multi-Lon does not suffer from limitations that prevent general service use. Multi-Lon consists of inter-braided, continuous, synthetic thermoset fibers immunized with PTFE lubricant and a special silicone-free, break-in, sacrificial lubricant.
Unlike many synthetic yarns, it does not cause severe scoring
Does not cause electrolytic pitting like carbon or graphite yarns
Does not have the shaft speed limitations or the elongation/ extrusion problems often associated with PTFE fiber yarns
Chesterton 1830SSP Slurry Pump Packing is manufactured with a hybrid yarn, combining advanced, expanded, graphite PTFE yarn with carbon yarn reinforcement. This unique construction of yarns yields a packing that is easily removable during repack, resulting in reduced downtime. 1830SSP can be used in a wide range of slurry sealing applications, from a submersible slurry pump to a mining slurry pump.
Chesterton 1760 is a unique packing consisting of a PTFE yarn lubricated with graphite particles that dissipate heat. The finished packing is further lubricated with a special silicone oil for quick break-in.
Inter-Braid Construction; Superior Tensile Strength
Chesterton 412-W combines a newly developed synthetic composite yarn with a specially formulated break-in lubricant. Continuous filament center provides 10 times the tensile strength of typical packing fibers.
Fibrous covering enables 412-W to absorb twice the PTFE blocking agents of conventional packing
Chesterton interbraid construction helps prevent migration of blocking agents so that 412-W maintains density to prevent wicking throughout its service life
Incorporates a purified colloidal lubricant to prevent failure at start-up and maintain continuous lubrication throughout the break-in process
Structurally-Reinforced Graphite Packing Ideal for Demanding Applications
Chesterton GraphMax is an interbraided graphite packing. Carbon yarns are incorporated in the braided structure in a way that allows very tight braiding and corner reinforcement that improves the strength of the packing. This dramatically improves the packing’s resistance to extrusion and blow out, one of the limitations of traditional, flexible, graphite tape packings.
GraphMax can be used in demanding rotating applications such as those in the power, pulp and paper, and ore processing industries where temperature and pressure resistance can be required in combination with chemical and abrasion resistance.
GraphMax’s applicability in valves makes it a convenient plant-wide general service packing.
Chesterton 477-1 carbon fiber packing combines a new yarn formulation with superior blocking agents. New, low modulus yarn provides the strength associated with continuous filament carbon fibers plus greater flexibility. This makes 477-1 strong, yet pliable, without the brittleness of conventional carbon packing.
Chesterton 477-1 incorporates a high-purity dispersion of inorganic platelets which prevent penetration of gases or liquids through the packing. Inter-braid construction locks these blocking agents within the packing ring.
Best Choice for High-Temperature and High-Pressure Applications
Reinforced, braided, graphite packing with a corrosion inhibitor. The carbon yarn reinforcement is provided within the graphite tape yarn as well as the braided construction.
1400R forms a homogeneous mass under gland pressure, so that leakage cannot penetrate the packing set.
The all-carbon/graphite set withstands higher shaft speeds while limiting shaft friction.
The structural carbon fiber reinforcement prevents extrusion when 1400R sets are installed in valves at higher pressures.
In addition to its excellent sealing capabilities in rotating equipment, 1400R is a superior valve sealing material. This dual purpose design makes it a truly universal mechanical packing.
Innovative Packing Technology for Longer Life in Severe Slurry Applications
Until now selecting the correct packing for your application has been a balancing act between different materials. Aramids are tough and resilient but have high friction and fret shafts and sleeves, and PTFEs are extremely low friction and kind to shafts but can consolidate and extrude. All of these issues cause a loss of compression, resulting in leakage and requiring packing adjustments.
Chesterton DualPac® 2211 is built to address these issues by combining two complimentary materials in one packing. Using the patented braiding technology graphite filled ePTFE can be placed against the shaft where it provides superior sealing and low friction, and a high strength and resiliency aramid is placed against the stuffing box bore to resist consolidation without shaft wear. Both lab and field tests have shown that DualPac requires fewer gland adjustments, resulting in drastically extended life in severe service applications.
This unique, carbon and graphite construction packing provides plant-wide utility off a single spool. Chesterton 370 is manufactured from a high-quality carbon yarn incorporated with particles of pure graphite, high-temperature tolerant oils, and molybdenum disulfide, all of which act as long-life lubricants and blocking agents. The low-friction carbon yarn has exceptional high-temperature capability in a non-oxidizing environment.
Chesterton 1765 is ideally suited for bleach pumps and other rotary applications requiring a white, non-staining packing. Constructed from chemically resistant, expanded PTFE material, this packing demonstrates higher speed performance capabilities than traditional PTFE materials for improved performance in a wide range of applications. Chesterton 1765 is ideal for rotary applications where chemical resistance is required and process needs to remain non-contaminated, such as ClO2 pumps, paper stock, and feeders.
Chesterton 1730SC packing combines a resilient silicone rubber core with the heat-resistant thermoset fiber of Chesterton’s MillPack 1730. The elastic, rubber core gives the packing better memory, allowing it to withstand radial shaft motion and vibration while maintaining excellent leakage control with minimal gland adjustments.
Rugged as well as easy to use and break in, 1730SC is designed for use in general service rotating equipment such as agitators, blenders, mixers, or any other applications that undergo shaft deflection in normal operating conditions.
Chesterton 1740 is an inter-braided packing using aramid fibern with PTFE and other lubricants.* Each strand of yarn has been individually coated in order to dissipate heat. 1740 can be installed as full sets to offer combined resistance to pressure, temperature, chemicals, and wear. 1740 braided packing is also used as back-up rings for added extrusion resistance in abrasive applications.

Developed for the tough applications in the pulp and paper industry, 477-1T is specially designed to be used in high pressure feeders, pre-steaming vessels and applications that are moving abrasive slurries. This packing’s combined force of carbon yarn and PTFE dispersions increases its chemical resistance against strong caustic and acid mediums.
Chesterton 477-1T is also an excellent bottom anti-extrusion end ring when coupled with Chesterton 1400R Carbon-Reinforced Graphite Packing in rotating equipment. This combination is ideal for reducing or eliminating flush water from a stuffing box.
Chesterton 329 Stern-Lon® is square-plait-braided to provide an unusually flexible, formable shaft packing. The base fiber is a long-fibered, roved flax of the highest quality. 329 is graphite-free to avoid galvanic corrosion on shafts.
During production, 329 is first impregnated with concentrated PTFE dispersion to promote non-flowing lubricity and to retard degradation. This is followed with a plasticizing “break-in” lubricant which assures compressibility, flexibility, and good packing-to-shaft contact. Large sizes need not be hammered into place. Finally, to minimize frictional attrition, a finely divided fluorocarbon powder is embedded into the surface of the packing. Chesterton 329 produces little or no shaft or sleeve wear.

Chesterton SuperSet Total Sealing Solution Featuring SpiralTrac
Chesterton SuperSet Total Sealing Solution Featuring SpiralTrac
Packing Sets with Solids Excluder for Longer Packing Life
The Chesterton SuperSet™ combines the superior sealing capabilities of Chesterton’s compression packing products with the patented design of the EnviroSeal SpiralTrac™ Version P Environmental Controller for packed stuffing boxes. This total sealing solution set is proven to increase packing and equipment service life while dramatically reducing flush rates.
The SpiralTrac Version P actually enhances the utilization of the flow and centrifugal effects around the shaft; it performs similarly to a centrifugal separator.
The built-in tangential lantern ring and helical grooving system impart motion to the flush, and the resulting centrifugal force throws the particulates in the fluid to the outside of the bushing.
The patented SpiralTrac grooving system then hydro-dynamically pumps the solids to the bottom of the stuffing box and back out into the pump casing.
The ability to remove particulate from the stuffing box is what differentiates the SpiralTrac from plain restriction bushings on the market today.
Chesterton offers six high-performance compression packing options in the SuperSet that cover a complete range of applications while meeting the needs and requirements of various industries (see Technical Data below).
Chesterton Rotary Live Loading is a technology that extends time between packing adjustments by extending the travel in the bolts with disc spring assemblies. Rotary Live Loading consists of springs, stainless steel washers, and inner (or outer) guides. Rotary Live Loading also assists pump applications with harmonics / vibration issues by keeping the load on the gland at a more steady state.
