SES 300 Series
The Chesterton SES 200 Series features high-performance elliptical spring-energized seals ideal for rotary, reciprocating, and static applications where equipment tolerances vary or compact seal designs are needed. Its oval-shaped spring provides even sealing force across the seal circumference, compensating for wear, misalignment, and temperature-related changes while ensuring a tight, reliable seal.
Manufactured from advanced polymer materials and precision-machined to fit demanding hardware geometries, the SES 200 seals excel in miniature or high-tolerance environments. These seals are suited for applications ranging from small medical and instrumentation devices to large industrial systems, delivering low friction, excellent chemical resistance, and long service life even in harsh conditions.
