Pump Packing 

1830-SSP Slurry Packing

Chesterton 1830-SSP 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. 1830-SSP is applicable in a wide range of slurry sealing applications.


  • Advanced Expanded Graphite PTFE, Carbon Reinforced Packing
  • Developed to meet rigid demands of slurry sealing applications
  • Low friction, less heat generation non-abrasive, saves shafts and shaft sleeves
  • Low leakage and long life


2211 DualPac Severe Slurry Packing

Chesterton​​ DualPac™​ 2211 mechanical packing is built to address these issues by combining two complimentary materials in one packing. Using Chesterton's 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.​


  • Achieves significantly longer packing life
  • Low friction and gentle on shafts​
  • Resists consolidation and extrusion​​​​
  • Multiple configurations to eliminate need for end rings
  • Exclusive design using DualPac packing technology​​​​​​​​​​​



425 Food Grade PTFE Filament Packing

Chesterton 425 is manufactured with a virgin PTFE filament and a white oil lubricant. It is perfectly suited for use in valves and also in rotating equipment such as blenders, mixers, agitators and other rotating equipment. Chesterton 425 complies with the USDA requirements for minimal food contact and FDA specification 21 CFR, 178.3620 for lubricants with incidental food contact as well as 177.1550 perfluorocarbon resins.


  • Meets USDA requirements
  • Meets FDA requirement 21 CFR 178.3620 and 21 CFR 177.1550
  • For use in pumps, valves and other rotating and reciprocating equipment



1730 Synthetic Non-Staining Fiber Packing

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 packings, even at high shaft speeds.


  • Excellent Leakage Control
  • Non-staining
  • More Rugged than PRFE Fiber Packing
  • Resists Heat Damage and Glazing
