Utilizing a Helical wound spring in combination with a PTFE Seal jacket will profit from a good static seal ability and slow dynamic seal ability.
The Helical wound spring characteristics allows for a high spring force at a low compression rate compared V-spring energized seal.
These characteristics make it more suitable for applications with large temperature spans and extreme temperature applications example cryogenics.
Accofluor can supply a large range of helical wound spring activated seals. Helical wound spring activated seals are not suitable for rotation or highspeed applications.
