ABSTRACT:
A rod seal for establishing a seal between an elongate rod and a housing wall around an enlarged opening in the wall through which the rod projects provides a close fitting sliding seal between the rod and the seal to accommodate longitudinal reciprocation of the rod relative to the seal and housing and also provides a sliding seal between the seal and housing wall to accommodate lateral movement of the rod relative to the housing. The sleeve is of a two piece construction which is assembled by a snap fit after the rod has been inserted into one element of the seal so that an enlarged end of the rod may be passed through an opening in the one seal element and the subsequent assembly of the second element achieves a close sliding fit with the unenlarged diameter section of the rod.
