Design Features

Fits Narrow Stuffing Boxes Seal sizes 1” through 1-3/8” (inclusive) require a 5/16” cross section, and sizes 1-1/2” through 2-5/8” (inclusive) require a 3/8” cross section. Slotted Glands The HOS design features a slotted gland that offers more versatility with bolting patterns. Impeller Adjustments In Service Disassembling the pump is unnecessary to make impeller clearance adjustments. 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.
