Abstract
An integral sealing system for a cylinder or piston rod and the like, for bearing, sealing and wiping a piston rod during reciprocating motion, is a molded polymeric unit. The integral system includes a body terminating at one end in a divergent pair of generally axially-extending annular tapered lips, the outer surfaces of the pair of lips defining sealing surfaces. The body of the integral system terminates at the other end in an inwardly tapering surface and protruding lip for wiping of the rod surface to exclude contaminants.
