Abstract

See full text

A fluid seal made of elastomeric material for use between an external stationary member and a rotating internal member avoids use of a customary pressed steel case. The seal may be stretched over an external flange on a rotatable shaft and recover from the elongation to the designed dimension at which the seal is to operate within the external stationary member. A specially formulated elastomeric composition accommodates elongation during stretching in excess of 300%.
