How Do Spring-Energized Seals Work

Spring-energized seals provide durable and reliable sealing solutions in critical applications and under extreme operating conditions in different industries.

Different Springs for Different Applications

D Eleven Tech offers three different types of springs that can be used in seals.

Cantilever V-Spring

Canted Coil Spring

Helical Ribbon Spring

Typical material grades are:

PTFE (virgin and filled versions) + Spring

PEEK compounds (unfilled and filled versions) + Spring

When the seal is installed into the seal cavity, the seal lips and spring energizer are deformed/compressed in radial direction. The spring energizes the jacket, providing resilience to lips (pushing the the seal lips out) and resulting in an effective sealing device in dynamic and static applications.

Radial tension (generated and maintained by the spring in the seal sleeve) keeps the seal lip in contact with the mating surface (providing good low pressure sealing capability even before system pressure is applied)

When system pressure is applied, the action of the spring increases.

D Eleven Tech supply the spring energized seals as per your working environment and drawing with confidence.
