SES 500 Series
The Chesterton SES 500 Series combines durable spring-energized V‑rings and polymer components to deliver robust sealing for deep-stuffed shafts in both rotary and reciprocating equipment. Built to handle tough service, this versatile stacked design is available in solid and split configurations to fit a wide range of hardware, making field installation and maintenance significantly easier—often without equipment disassembly.
Constructed from engineered plastics and PTFE blends with multiple spring energizer options, the SES 500 Series provides a consistent sealing force that adapts to system pressure. It operates across extreme temperature ranges (from −156 °C to +200 °C) and accommodates diverse pressures and media types. Ideal for applications like slurry pumps, heavy-duty industrial cylinders, and high-pressure dynamic systems, these seals deliver long service life, reduce leakage, and cut maintenance needs.
