A ring seal for protecting a designated area from ambient contamination is alternately placeable into its sealing and non-sealing positions. The ring seal permits a limited travel between the sealable surfaces without compromising the seal integrity. The ring seal facilitates an interference-free installation and selective maintenance of the sealable parts.

A check valve assembly regulating the fluid flow between the fluid reservoir and filter cartridge chamber is actuated by a valve actuating member movable through and controllable exteriorly of a filter system housing without compromising the housing leak integrity. The actuating member may perform another function of a drain plug for the filter chamber, so that upon removal of the member the check valve assembly will be closed and the chamber fluid drained through a drain plug opening without loss of the reservoir fluid.
