Chesterton 155 Standard Single Cartridge Seal

Chesterton 155 Standard Cartridge Single Seal
A Flexible Single Mechanical Seal for Plant-Wide Use

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​The Chesterton 155™ cartridge-style single seal is the perfect seal 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.

With the addition of the adjustable gland tabs, the Chesterton 155 can adapt to any bolting pattern, making installation easier.
