ABSTRACT:
A sealing apparatus includes a sealing arrangement and a groove in a base. The sealing arrangement may comprise an o-ring and a grounding gasket where both the o-ring and the grounding gasket partially protrude in a longitudinal direction from the groove. Thus, the grounding gasket, which is equipped with ends that can be pulled out of the groove, can be removed from the groove by a pulling force. This leaves the o-ring accessible for removal or maintenance at a much lower cost in terms of manufacturing and operational costs. The sealing arrangement may also include inner and outer o-rings which seal a fluid flow from the atmosphere.
