Abstract
A push-pull rod assembly is provided with a housing for the push rod and a seal formed in a capsule readily fixable to a fitting associated with the housing. In one embodiment the housing is formed with a flared end while the fitting, which has a threaded outer surface, is formed with an interior bore therethrough and an axially intersecting cone shaped bore adapted to engage the outer flared surface of the housing. The bore sealing capsule carries an elastomeric seal to sealingly surround a push rod extending outwardly of the housing while the capsule is threadably engaged with the fitting. The capsule is formed with a frustoconical projection axially centered at the base of an interior threaded socket to engage the interior of the flared end of the housing. In the second embodiment the push rod is specially coated with an inert synthetic resin having a low coefficient of friction. The sealing means which is contained in a capsule threadably engaged on a fitting fixedly associated with the push rod housing includes an elastomeric member or the like and a metallic scraper to remove dirt and ice from the specially surfaced push rod.
