ABSTRACT:
In the art of pressure shaft seals, a method for sealing including installing a seal having a reinforcing shell with a cylindrical portion and a radial portion wherein the pierce or endwall of the radial flange is formed as a radius or taper facing axially inwardly, instead of as a cylindrical surface parallel to the seal axis, to reduce the shear pressure on the bond at the pierce and also to eliminate a sharp corner and any tendency of the rubber to tear, and wherein an offset is provided on the axially outer surface of the radial flange of the metal case adjacent the pierce to disturb the flowing rubber from wiping the bonding cement off of the pierce.
