Spring Energized Seals Manufacturer

Custom spring energized seals with in-house spring energizer manufacturing for demanding static and dynamic applications.

Hansealing manufactures spring energized seals for applications where conventional elastomer seals may not provide the required combination of chemical resistance, temperature capability, low friction, pressure  resistance or long-term reliability.

Each seal combines a precision-machined polymer jacket with an internal metallic spring energizer that provides initial sealing force and helps maintain contact as operating conditions change.

Unlike suppliers who source the energizer separately, we manufacture both the spring energizer and the finished sealing component in-house. This gives us greater control over spring design, material selection, seal configuration, customization, production lead time and cost.

PRODUCT POSITIONING

Spring Energized Seals: Polymer Jacket + Spring Energizer

A spring energized seal combines a polymer sealing jacket with an internal metallic spring energizer.

The jacket provides the sealing interface and contributes to chemical, temperature and friction performance. The spring energizer maintains sealing contact as operating conditions change.

Seal performance depends on the interaction of the jacket, spring energizer, seal profile and hardware.

OUR RANGE

Find the Right Spring Energized Seal

Choose a spring energized seal by spring energizer, seal profile, sealing type or application type.

BY SPRING ENERGIZER

By Spring Energizer

Different spring energizers provide different combinations of sealing force, deflection, friction and dynamic performance. Choose the spring configuration according to your sealing requirements and operating conditions.

Helical Spring Seals

Helical spring seals use a wound metal spring to provide relatively high sealing force within a controlled deflection range. They are well suited to applications where positive sealing contact is more important than minimum friction.

Helical Spring Energizer Seals

Canted Coil Spring Seals

Canted coil spring seals use a precision-formed coil spring to provide consistent sealing contact over a broad deflection range. They are a versatile choice for dynamic applications where controlled friction and reliable contact are important.

Canted Coil Spring Energizer Seal

Cantilever Spring Seals

Cantilever spring seals use flexible V- or U-shaped spring configurations to maintain sealing contact with controlled spring loading. They offer a practical balance of sealing force, friction and movement tolerance across a range of static and dynamic sealing applications.

SEAL CONFIGURATIONS

Special Seal Configurations

Some applications require more than a standard radial seal profile. Hansealing offers specialized seal configurations for installation constraints, anti-rotation requirements, face sealing and other application-specific needs.

Flanged Seals

Flanged spring seals incorporate a flange that can be retained by the gland to help control seal movement or rotation. They are particularly useful when the seal requires additional mechanical retention within the hardware.

Flanged Spring Seal

O-Ring Heel Seals

O-Ring heel seals incorporate an O-ring at the heel of the seal to provide additional retention and resistance to seal rotation. They are useful where the gland configuration allows space for the integrated heel O-ring.

O Ring Heel Seal

O-Ring OD Seals

O-Ring OD seals use an O-ring on the outside diameter of the seal to provide additional retention and sealing support. This configuration can be considered where the surrounding hardware and gland design allow an OD O-ring.

BY SEALING TYPE

By Sealing Type

Spring energized seals can be selected according to the sealing location and hardware arrangement, including rod/shaft, piston/bore and axial face sealing.

Rod / Shaft Seals

For sealing against shafts, rods and other moving or stationary cylindrical surfaces.

Rod / Shaft Spring Energizer Seals

Piston / Bore Seals

For piston and bore applications where the seal contacts the housing or cylinder surface.

Piston / Bore Spring Energizer Seals

Internal Face Spring Seals (For axial sealing applications)

Internal face spring seals are designed for axial sealing with pressure applied from the internal side of the sealed assembly. They are commonly used where a face seal is required instead of a radial sealing arrangement.

Internal Face Cantilever Spring Seal

External Face Spring Seals (For axial sealing applications)

External face spring seals are designed for axial sealing with pressure applied from the external side of the sealed assembly. They provide an alternative to radial sealing where the hardware is configured for an external face seal.
