Pro​viding Value to Industry Since 1884

Arthur "A.W." Chesterton launched Chesterton Company, a purveyor of steamboat and engineering supplies, on the Boston, Massachusetts,​ waterfront in 1884. His focus much as the company operates today was connecting customers quickly to the product solutions they needed, and this approach was met with success. Before long, the company became a manufacturer as well a distributor.​


Pump Packing & Gasketing​

Chesterton introduced its own line of pump packing and gasketing ​and the company's focus on industrial sealing solutions was born. Over the next few decades, the organization introduced a number of advanced packing products resistant to high te​mperatures and chemical exposure.


International Expansion

Chesterton evolved to include​ national distribution in the United States and by the 1950s the company was expanding internationally with sales and manufacturing in Mexico and distribution in Asia (Japan).


Mechanical Sealing

The 1960s saw Chesterton venturing into the mechanical seals arena. By the mid-1980s, Chesterton had launched over 8 innovative mechanical sealing solutions, including the first off-the-shelf single cartridge mounted seal and the first commercially viable split mechanical seal, which eliminated shaft wear and hours of costly equipment teardown.​

​Over the decades, Chesterton added industrial lubricants and cleaners to its equipment prot​ection offerings, and started up a hydraulic sealing business that included developing proprietary, high-performance polymer materials.


Over a Century of Achievements

By 2000, Chesterton employees could look back on a long history of award-winning mechanical seals, pump packings, hydraulic seals, and lubricants, including many Vaaler awards, two seals named "Product of the Year" by Plant Engineering in 1992, the flagship 442™ Split Mechanical Seal, and the first braided graphite tape packing guaranteed to meet the stringent Clean Air Environmental Standard.

Solution and Knowledge

Chesterton has grown ​from a manufacturer of sealing devices to a comprehensive solutions provider for plant equipment reliability and efficiency, improved plant maintenance, and reduced use of natural resources.
