Abstract
An end cap for a pressure vessel has at least one part for connecting the end cap to a housing. The at least one part comprises a number of recesses. The recesses are arranged to form at least one fluid passage between an inside and an outside of the end cap when the end cap is plugged on the housing. A housing for a pressure vessel has at least one counterpart for connecting an end cap to the housing by engaging a part of the end cap. The at least one counterpart comprises a number of recesses. The recesses are arranged to form at least one fluid passage between an inside and an outside of the housing when the end cap is plugged on the housing. A method for leak testing a pressure vessel and a method for checking a connection between at least one end cap and a housing of a pressure vessel for leak tightness are also described.
