HB BESTSEAL designs and manufactures SES - Spring Energized Seals - in a wide range of PTFE and HPP - High performance polymers - materials, thanks to their high performances. This spring energized seals are suitable for the following industrial and engineering applications.
Our spring energized seals are used in:
- Aero hydraulics & Pneumatic Systems
- Coolers
- Cryogenic Swivels
- Diesel Engines
- Filling Machines
- Flange connections
- Fuel Control Systems
- Gas Turbine Engines
- HPLC Pumps
- Laboratory equipment
- Low Friction Pneumatics
- Medical & Laboratory Instrumentations
- Oil Field Equipment
Spring energized seals provide durable and reliable sealing solutions in critical applications and under extreme operating conditions in different industries.
This seal design extends the operating limits of polymer-based seals by:
- Providing gas-tight sealing systems to end-users
- Helping to achieve fugitive emission reduction goals
- Meeting environmental regulation requirements
Spring energized seals are a highly reliable option when standard elastomer-based and polyurethane-based seals will not meet the operating limits, equipment parameters, or environmental conditions of your application. Even when a standard seal might meet basic needs, many engineers turn to spring energized seals for an added level of reliability and peace of mind.
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.
How Do Spring Energized Seals Work?
Spring energized seals are generally manufactured from high-performance fluoroplastic compounds and engineered plastics.
Typical material grades are:
- PTFE (virgin and filled versions)
- PEEK compounds (unfilled and filled versions)
These materials have outstanding physical and technical characteristics, but they are not elastic. They are better characterized as rigid. That is the reason why different type of springs must be used to mechanically energize the seal lips. So the technical term "Spring Energized Seal" reflects on the design/construction of the sealing device, where the spring compensates for polymer materials with low memory/elasticity.
Seal Jacket Materials
The seal jackets in spring energized seals are made of various high-performance materials:
- Fluoroplastic compounds
- Engineered plastics such as UHMWPE, PEEK, TPE, PCTFE, etc.

A spring-energized seal consists of a high performance polymer sleeve and a finger spring. The polymeric sleeve has a U-shaped profile and it can be made of PTFE, PTFE Carbon, PTFE Graphite, PTFE Bronze or PTFE Glass. The finger spring can be a V-spring (meander spring), Helical spring or canted coil spring. The spring materials can be made of stainless steel, PEEK or Inconel.
This type of seal is capable of handling extreme service conditions, such as ultra-low friction, chemical compatibility and extreme temperature is required. The spring will energize the sealing lip even at low pressure and also at high pressure. It was designed especially for turbine engines, rockets, missiles, and also to serve the most challenging oil and gas applications.
