ABSTRACT:
Shaft seals of the lip type with a sealing member bonded to an apertured insert have a tendency to form blisters in the sealing member near the bond. In order to avoid this, and provide a seal suitable for use in hygienic environments, the sealing member is mechanically engaged with the insert, for example, by being in the general form of a grommet with a central boss filling in the aperture and carrying the sealing lips, and having a wide radial flange forming a cleanable face exposed to the process fluid and a narrow deformable flange adapted to pass through the aperture of the insert and to expand into mechanical engagement therewith.
