Enhanced Design for Simple Installation and Greater Sealing Reliability

​​​Groveland, Massachusetts, USA—April 2, 2014

The Chesterton 442C™ Cartridge Split Seal is the latest innovation in split seal technology, combining superior seal performance with the ease of installation of a cartridge split seal. Engineered using the global leading 442 Split Seal platform, Chesterton maintained all the significant form and fit capabilities of the 442 Split Seal while simplifying installation and enhancing seal performance.

​Innovation Drives Performance

The 442C incorporates many new technical innovations that simplify seal installation and increase seal performance and reliability.

This ensures proper face alignment which critical to sealing success. Springs energize after installation allowing for maximum space between seal faces during installation, simplifying seal installation.

With only two seal components, the 442C Cartridge Split Seal is easy to install, offers the greatest installation flexibility, and is engineered to enhance sealing reliability like no other cartridge split seal.
