Chesterton 477-1 Carbon Fiber 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.
Features & Benefits
- Strong, yet pliable, staple carbon yarn
- Unique inorganic blocking agent stops gas/liquid penetration
- Molybdenum-based corrosion inhibitor prevents stem pitting
-
Chesterton 477-1T Carbon/PTFE Packing
Chesterton 477-1T is a tough, yet pliable, continuous filament carbon yarn packing impregnated throughout with PTFE to provide a non-contaminating, non-staining carbon yarn packing. 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.Features & Benefits- Non-contaminating, non-staining carbon yarn packing
Unique inorganic blocking agent stops gas/ liquid penetration - Molybdenum-based corrosion inhibitor prevents stem pitting
- Non-contaminating, non-staining carbon yarn packing

Chesterton DualPac® 2212 Packing
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 our 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
- Minimizes shaft scoring
- Requires less overall maintenance

Chesterton GraphMax Packing
Chesterton GraphMax is an inter braided 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.
Features & Benefits
- Exclusive construction for plant-wide use in pumps and valves
- Maintains structural integrity for easy removal
- Carbon fiber-reinforced graphite strands provide maximum extrusion resistance and high-pressure capability

Chesterton NSF 61 Seals
Chesterton Expands NSF 61 Certification to All Single Cartridge and Split Mechanical Seals
To meet the growing demand for certified drinking water supplies, Chesterton has expanded its offering of NSF 61 certified mechanical seals to include all its single cartridge seals as well as split seals.
Developed by a team of scientists, industry experts and key industry stakeholders, NSF/ANSI/CAN 61 sets health effects criteria for many water system components. The majority of water treatment or distribution products in North America are now required to comply with NSF/ANSI/CAN 61: Drinking Water System Components – Health Effects by governmental agencies that regulate drinking water supplies.
Previously, Chesterton’s NSF products were limited to the 155 Single Cartridge Seal and the Chesterton 442 with RSC faces. The company recently received approval for ALL Chesterton single cartridge seals as well as its flagship Chesterton 442 and 442C split seals.
The certifiable seal configurations are as follows:
- 155, 150, S10 (Seal Faces: CB/SSC EP, SSC/SSC EP) including variants
- 442C, 442 (Seal Faces: CB/RSC EP, RSC/RSC/EP) including variants
Chesterton also offers an industrial coating NSF 61 certified product, ARC S1PW, which protects pipes and other structures against erosion, corrosion, and chemical attack.

Chesterton SuperSet Total Sealing Solution Featuring SpiralTrac
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
Features & Benefits- Reduces flush water consumption
- Increases equipment MTBR; extends packing life 2 to 6 times of traditional packing
- Reduces shaft sleeve wear
- Reduces number of packing rings
