Description

The TSHS seal is particularly suitable, in the absence of external washing, for non-toxic and non-polluting fluids which crystallize in contact with the atmosphere; the stationary bellows excludes spring and dynamic o-ring packing problems and tolerates axial and radial movements.

The seal equipped with secondary graphoil gaskets is recommended for fluids with temperatures higher than 260° C.
The balanced cartridge solution is equipped with a floating containment bush for physiological losses of the seal.
The TSHS seal is the result of the standardization of a series of projects tested and created in accordance with the API 682 IV edition standard.
