- Cartridge Mounted
- The seal is pre-assembled at the factory, mounted on its sleeve and installed in the gland for easy installation.
- No Installation Measurements — Mechanics are not required to make critical installation measurements in order to install the seal.
- No Shaft Fretting Wear — No shaft fretting wear occurs, because the O-ring on the shaft is static and does not move.
