Disclosed is a static seal suitable for sealing a pull rod or the like to an opening through which the rod passes into a hydraulic conduit. This static seal can be used in a wide variety of apparatus including for example spray coating guns, both electrostatic and non-electrostatic, valve assemblies and the like. Novel static sealing arrangements at each end of a non-machined extruded bellows provide packingless bellows sealing between the rod and the opening. Such a sealing arrangement is compatible with the highly desirable materials of the fluorinated hydrocarbon group, commonly known by the trade name Teflon.
