A filter assembly comprising:
- a manifold comprising a housing having threads;
- a filter bowl comprising (i) respective threads configured to engage with the threads of the housing as the filter bowl is screwed into the housing, (ii) a ramped surface, and (iii) a notch;
- and
- a locking mechanism comprising a pawl, wherein as the filter bowl is screwed into the housing, the pawl traces the ramped surface, and wherein the pawl engages the notch after the pawl has moved past the ramped surface to lock the filter bowl to the manifold.
A method comprising:
- aligning a filter bowl with a housing of a manifold, wherein the housing comprises threads, and wherein the filter bowl comprises respective threads and a notch;
- screwing the filter bowl into the housing by engaging the respective threads of the filter bowl with the threads of the housing;
- delaying engagement of a pawl of a locking mechanism with the notch until the respective threads of the filter bowl has achieved substantially-full thread engagement with the threads of the housing;
- and
- engaging the pawl with the notch to lock the filter bowl in position and prevent the filter bowl from being unthreaded.
