Abstract
A combined packing nut and rod guide for piston paint pumps has a body with a central bore therethrough and at least one relief extending axially along the bore providing a lubricating passageway and paint leakage path. An annular reservoir is formed at an interior end of the nut body for lubricating fluid. The nut body has axial and radial surfaces to axially and radially position the combined packing nut and rod guide in the pump housing to locate and maintain the position of the piston rod with respect to the housing.
