A spring-energized seal consists of three main elements: a jacket, a spring and high performance plastic sealing materials. It uses a spring to provide a consistent load throughout the circumference of the seal. This way a leak-tight seal is created between the jacket, made out of high performance plastics, and the hardware. The choice of high performance plastics provides outstanding physical and mechanical characteristics.
Spring-energized seals are typically encountered in environments that place too much strain on conventional elastomeric seals: extreme temperatures and pressures, high levels of friction and wear or aggressive media are among the most common. Because the high performance plastics for spring-energized seals are machined, the seal configuration can be altered to meet to your specific needs.
Spring Load
A stainless steel spring energizes the seal and supplies all of the load needed for sealing when the media pressure is too low to fully actuate the lips.
The spring also makes up for variations in gland tolerance and normal seal wear. As a seal loading device, a metal spring is more accurate than devices such as O-rings for controlling friction. There are three different spring types, each with one to three different load ratings (light, medium and heavy) to meet the exact linear friction or torque requirements.
In dynamic applications, the spring expands to offset seal wear while continuing to provide load. In conditions involving thermal cycling, the spring system continues to energize the seal lips without taking a compression set or becoming too soft or hard, the way an elastomer can.
The flexible spring allows for an extensive tolerance range that can help surmount hardware misalignment and eccentricity, without causing added friction or the inability to seal. Three different spring energized PTFE seal designs are available, offering individual attributes for each application.
Spring Energized Seal Design
Basic design parameters of spring energized seals:
- Made from high-performance fluoroplastic compounds and engineered plastics that have outstanding physical and technical characteristics, but are rigid rather than flexible.
- Use springs to provide a consistent load throughout the circumference of the seal and create a leak-tight seal between the jacket and the hardware.
- Use system pressure to create an additional sealing force between the jacket and the hardware.
- In this combination, the spring forces the seal lips against the gland and rod surfaces, while pressure assists the spring force.
- The result: virtual leak-free sealing, high reliability, longer asset life.

- Wide temperature range
- Exceptional chemical and corrosion resistance
- High surface speed capability
- Suitable for dry operation
- Low coefficient of friction
- FDA approved compounds possible
