BP File No. 2755-044 - 14 - ABSTRACT OF THE DISCLOSURE An annular fluid seal made of an elastomeric material has a body with a radially outer surface and a radially inner surface. The outer surface is contoured to be insertable into the opening in the end of a cylinder. The inner surface has at one side a radially inwardly extending sealing lip for slidably engaging and sealing a piston rod, and at the other side it has a radially inwardly extending wiping flap for wiping the piston rod. between the sealing lip and the wiper flap is a radially inwardly extending guide member slidably engaging the rod for guiding the rod through the seal. The guide member is much wider than the sealing lip ox wiper flap, to withstand radial forces imposed by the rod which would otherwise tend to distort the seal and cause it to leak.
