ABSTRACT:
The spring installed on the sealing element of a seal is positively retained during shipping, handling and installation by covering the spring and at least adjacent portions of the sealing element with a film of wax. In the preferred embodiment of a lip type seal including a metal casing and an elastomeric sealing element having a garter spring installed thereon, the entire head section and spring of the seal are covered with a film of wax by immersing the head section in a melted wax-like substance. The wax film positively retains the spring and also provides lubrication to the sealing lip during initial installation and start up.
