FS Casing & Tubing Seal FS seals

FS seals is designed to provide high performance static sealing against rough casing and tubing. It reduces installation time, correct placement in the housing and simplify installation method.

The FS seals technology is especially suited for applications where wide tolerances and varying surface finishes create difficult sealing conditions. It is utilized as a large cross-section interference seal to bridge large extrusion gaps associated with sealing on rough mill casing. The shape of the FS seals design allows for a high level of deflection across the full range of operating temperatures, without the risk of gland overfill.
