The patented Spheriseal allows a "hole” to be moved or tilted. As odd as this may seem, the Spheriseal has this capability due to the combination of a flat and spherical sealing surface. Because of these features, Spheriseals allow the use of precision shaft seals with vessel openings which are "as welded". The Spheriseal is available as a separate module, or it can be designed into another item such as a packing gland.
