Case Studies
Reduced Lead Times with Chesterton® Spring Energised Seals
Challenge
Background
A pressure relief valve manufacturer faced significant supply chain challenges with their previous spring energised seal (SES) supplier. Lead times exceeded 7 weeks, and high minimum order quantities of 1,000 seals forced excess inventory holding. Poor technical support further complicated their operations, leading to delayed shipments and increased costs.

Solution
Product
Chesterton® Elliptical Coil Spring Energised Seals (SES) 200 Series were implemented. The AWC540 graphite-filled PTFE jacket used provided enhanced wear resistance and chemical compatibility. Key features:
- Uniform load distribution from the elliptical coil design
- Enhanced thermal stability
- Unidirectional design for back pressure release
- High-pressure operational capability (150 psi in this case)
Support included field training and access to Chesterton University for the customer’s engineering team.
