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:

  • 180, 155, 150, S10 (Seal Faces: CB/SSC EP, SSC/SSC EP) including variants
  • 442C, 442 (Sea 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.
