Utilizing a Helical wound spring in combination with a PTFE seal jacket will result in benefits in the form of a good static, and slow dynamic seal.

The Helical wound spring’s characteristics allows for a high spring force at a low compression rate compared to a V-spring energized seal.

These characteristics make it more suitable for applications with large temperature spans and extreme temperature applications, such as in cryogenics.

Accofluor can supply a large range of Helical wound spring activated seals. Helical wound spring activated seals are not suitable for rotation or high-speed applications.
