Chesterton 225 Standard Cartridge Dual Seal
Flexible, Tandem Seal Design for Plant-Wide Use

  

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​The Chesterton 225™​ Standard Cartridge Seal provides a unique, effective solution for applications that require dual sealing with the flexibility to meet some of the most ​​challenging conditions.

The 225 Dual Seal features in-series (tandem orientation) configuration with both inboard and outboard sets of faces oriented in the same direction and the outboard faces sealing on the outside diameter. An in-series dual seal is recommended for higher-pressure applications, ​and, with its unique face design, it is also perfectly suited for applications with low emission requirements.
