DEFORMABLE TUBULAR SEAL MEMBER

摘要

A seal assembly (2) comprises a sealing part (4) having a deformable tubular seal member (6). The deformable tubular seal member (6) has a first end (6a) and a second end (6b). A central portion (6c) of the deformable tubular seal member disposed between the first end (6a) and the second end (6b) has a lower hardness than the first and second ends to form a seal of composite hardness. The seal assembly can be used to seal a cable in an aperture of a submerged turbine generator support pillar.
