Chesterton Increases Certifications

11 October 2019

Chesterton has expanded its offering of NSF 61 certified mechanical seals to include single cartridge seals as well as split seals to meet the demand for certified drinking water supplies. 

Up until this point, Chesterton’s NSF products were limited to the 155 Single Cartridge Seal and the Chesterton 442 with RSC faces. The company has now received approval for all Chesterton single cartridge seals as well as its flagship Chesterton 442 and 442C split seals.
