155 & 255 Cartridge Seals


A Flexible Mechanical Seal for Plant-Wide Use

The Chesterton 155 & 255 cartridge-style seals are the perfect seals for all of your general-purpose plant applications. This simple mechanical seal design results in a more robust and reliable seal for general applications, while the low profile seal faces allow for low heat generation—making it ideally ​suited for non-lubricating fluids.
