Seal

 

(also gland), a device to provide hermetic sealing in machine connections between rotating and stationary parts. This is accomplished using sealing rings, flanges, or other parts placed on the shaft or by means of various packings, such as asbestos, asbestos-wire, or fabric-reinforced rubber, embedded in the recesses or cavities of covers, housings, and similar parts.

Seal

 

any one mammal of the order Pinnipedia, which comprises the families Phocidae (true seals) and Otariidae (eared seals). The true seals probably descended from primitive Mustelidae, whereas the eared seals apparently are descendants of primitive bearlike creatures. True seals lack external ears, and both pairs of limbs are modified into clawed flippers. The hind limbs of seals are directed backward and serve for locomotion in water; they do not bend forward on dry land and cannot support the heavy body. There are about 20 species, belonging to 12 genera. Seals are widely distributed but are particularly numerous in polar latitudes. Most species form rookeries on the ice during the mating and molting period. The waters of the USSR are inhabited by nine species (in six genera), of which the harp seal, Caspian seal, ringed seal, Pacific harbor seal, and bearded seal are of commercial significance.
