Filtering arrangement including a non-reentrant shape

摘要

The disclosure describes a filter arrangement comprising a fitting and a filter assembly. The filter assembly includes an end tap and the end cap has a wall defining a bore. The fitting and the wall of the bore are fitted to one another by thermal expansion and contraction under elastic stress. At least one of the fitting and the wall of the bore has a non-reentrant shape shaped to resist longitudinal movement on the fitting within the bore and longitudinally secure and seal the filter assembly to the fitting.
