Chesterton 442C Cartridge Split Seal
Simple, Fast Installation and Greater Sealing Reliability

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​The Chesterton 442C™ Cartridge Split Seal combines superior seal performance with the ease of installation of a cartridge seal. Our patented split seal technology addresses the inherent limitations found in conventional cartridge split seal designs by minimizing installation complications and excessive leakage. As with all split seal options, it offers easy installation and replacement without the need for teardowns.

The 442C design also offers maximum installation flexibility with its short axial length and flexible gland positioning. It simplifies split mechanical seal repair by using a standard spare parts kit, enabling you to lower your inventory costs to maintain operations.
