Chesterton® 14K restriction bushings are designed for use in rotary equipment to form a barrier between the sealing device in the stuffing box or the pump impeller housing and the fluid in the mixing tank. The restriction that is produced reduces flush requirements and helps to prevent suspended abrasive particles from entering the stuffing box area.

This cartridge design uses high-performance, filled PTFE materials proven to withstand the high shear rates, frictional heat, and abrasives common when pumping high-viscosity products and dry powders.

Chesterton patent-pending 33K's split rotary seal design can be used on in many non-pressure applications including bearing protection for pumps, gearboxes and rollers. The innovative 33K split design eliminates the need and associated costs for equipment disassembly while improving seal performance of conventional lip seals. Installation time can be reduced from hours to minutes because the split assembly is unitized installing quickly and easily. 

Manufactured from advanced PTFE materials, this high-performance radial shaft seal has proven to outperform conventional rubber-based products under similar conditions. The Chesterton 30K seal offers excellent fluid compatibility, low friction, and outstanding performance for dynamic sealing applications.
