Springs come in different sizes and forms. To choose the right spring for your sealing application, it is essential to understand the characteristics of each spring.
The load versus deflection graph illustrates the behavior of each type of spring. Too much spring force can result in premature wear or excessive friction,
and too little spring force can lead to seal malfunction or poor contact in conductivity applications.
The graph below compares the behavior of Cantilever Springs, Helical Springs, Canted Coil Springs and Full Contacted Spring (further information available on request) which can help to navigate
the direction to choosing the right spring for your sealing application.

Cantilever spring |
|
| The Cantilever Spring has a large deflection range and is commonly used in spring energized seals. The V shape design is compressed during installation and provides spring load at the ends of the tabs. It is a great choice for medium load applications under static or low speed and is the preferred choice for reciprocating applications. |

|
Helical spring |
|
| The Helical spring has a high load spring with smaller deflection range. It distributes the load evenly across each individual band. It is commonly used for medium to high load applications under static and is recommended for vacuum and cryogenic sealing application. Helical spring can also be used by itself for other purposes, such as, EMI shielding or electricity conductivity reasons. Not suitable for wide gland tolerances, eccentricity, or misalignment. |

|
Canted Coil Spring for axial and radial application: |
|
| The Canted Coil Spring has a unique curve with a very flat spring rate in a specific working deflection range. It can be customized into differentspring loads. As the seal jacket wears, the force stays constant. It is typically used in dynamic with light to medium load application. Suitable for wide tolerance and glands. The design of the spring allows the spring to also perform outstanding tasks on its own such as electricity conductivity, EMI shielding, as well as mechanical fastening (locking, latching, and holding). |
