ABSTRACT:
A filter of the type used to filter gases or liquids has molded plastic end caps on each end of the filter element with the ends of the filter element molded into the end caps. To prevent the end of the filter element from being exposed through the exterior surface of one of the end caps, a spacer is located between the end of the filter element and the exterior surface of the end cap. The spacer allows the plastic material of the end cap to permeate the spacer to form a thin layer of plastic on the end of the filter element. This prevents thin spots in the end cap which could result in leakage through the end cap.
