280
High-Performance Seal for Critical Services and Hazardous Applications
The Chesterton 280 is a dual cartridge seal designed for severe-duty and environmentally sensitive applications. Built for reliability in high-temperature, high-pressure, and chemically aggressive environments, the 280 provides excellent containment and emission control.
Its robust construction and non-fretting design extend seal life and reduce maintenance in pumps, mixers, and other rotating equipment. With a compact footprint and modular design, the 280 is easy to install and maintain. It’s an ideal solution for industries where safety, compliance, and equipment uptime are essential.
