442C

Cartridge Split Mechanical Seal
The 442C Cartridge Split Mechanical Seal is the latest innovation in split seal technology combining superior performance with the ease of installation of a cartridge split seal. Our 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 seals, 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.
