Spring Energized Seals

Provides a Consistent Load for a Leak-Tight Seal

A Spring Energized Seal (SES) consists of a polymer jacket and a metallic spring. The spring provides a consistent load throughout the circumference of the jacket and creates a leak-tight seal to hardware. System pressure creates an additional force which further accentuates sealing.

Chesterton’s SES are precision machined to meet hardware requirements thereby providing optimal equipment performance. Whether the challenge is sealing harsh chemicals, high speed, extreme temperature, or high pressure, Chesterton Engineering can provide a high performance product to meet your system needs.
