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.

These wear rings reduce radial movement, therefore helping to extend seal life. The exceptional physical properties make them suitable for use on rams or pistons in reciprocating and rotary applications.Various designs and materials are available including the WR, P9KL, R9KL, WRTP, WRTR, WRUP, WRUR, which address specific needs and applications in the market.

The easy-to-use split 18K design is manufactured from a glass fiber-reinforced thermoplastic polyimide resin (heat stabilized nylon). These bearings reduce radial movement, helping to extend seal life. The easy-to-use split 19K is manufactured from a glass fiber-reinforced thermoplastic polyimide resin (heat stabilized nylon). These bearings reduce radial movement to help extend seal life. 

Chesterton 16K/17K non-metallic wear rings reduce the impact of transverse force on your cylinders to achieve improved service life and reliability.The split, continuous coil designs are made from a combination of composite polyester resin reinforced with synthetic fibers specifically designed to support heavy loads. The exceptional physical properties and built-in lubricants of these wear rings make them suitable for use on rams or pistons in reciprocating applications.
